Tin

This new ore generates above Deepslate, but below sea level in certain parts of the world, so you’ll have to venture out a bit from spawn to start finding it. But don’t worry, the closest Tin regions can be found only a thousand or so blocks from spawn. Once you find Tin, you can mine it using a Diamond Pickaxe or higher. This, combined with it only generating in some places, makes it more of an end game material rather than something you get immediately.

Tin itself also has some interesting properties. It is not magical at all, although it has an affinity for Redstone components, which generally involve winding up or responding to different levels of power.

Projectiles shot at blocks made of Tin will ricochet off of them. This even includes things like Potions, Snowballs and Llama Spit! Additionally, placing a block made of Tin next to another block will make the opposite side of that block deflective too. There are some substantial use cases like extending the range of ender pearls, along with potential for lots of silly minigames!

Tin Monolith

You may notice that deposits of Tin ore have a peculiar arrow shape… follow the arrows, and you’ll eventually encounter a massive Tin Monolith! Inside its crust of Cylindrite, the monolith is filled with Cassiterite and enough Tin ore to last you a long time - so you might want to set up camp!

Cylindrite

Cylindrite is a new stone type found only as the dark outer layer of the Monoliths. It can also be crafted with Deepslate and Tin! Cylindrite that generates above Deepslate is naturally smooth. Like many stones, it can also be turned into polished, brick, chiseled, and pillar variations!

Cassiterite

Cassiterite makes up the even darker inner layer of the Monoliths! It can be crafted with Granite and Tin and has a very similar blockset to Cylindrite.

Tin Chain, Tin Bulb, and Tin Bars

Tin Chains are a simple new decorative chain, much like Iron and Copper Chains; however, they look a bit thicker, making them ideal for bulkier designs. Tin Bulbs are much like Copper Bulbs, except they have fifteen light levels; every pulse increases it by one, until it resets back to zero. Tin can also be made into Tin Bars, like other metals!

Float Glass

A glassier (less visible) glass made from tin and amethyst, with Tin’s ricocheting property! Float Glass can also be also be crafted into Panes!

Hold Plate and Hold Button

Hold Buttons and Plates are the Tin variants of Buttons and Pressure Plates. Hold Buttons can be held down by holding right-click for any amount of time, only producing a short Redstone pulse once you let go. Similarly, Hold Plates will only produce a Redstone pulse once you step off of them.

Using a Comparator with these blocks allows you to count how long the button or plate has been held down for, at a rate of one pulse per second. If they are placed on a Gold Block, the rate will be one pulse every 0.5 seconds, and if placed on a Silver Block, the rate will be one pulse every 2 seconds.

Dimmer

A buzzy Tin light source that must be activated with a Redstone signal to stay on. Instead of powering up and down instantly like other Redstone lights, its brightness will change slowly and smoothly. The brightness that it reaches when powered is approximate to the signal strength. It can also be temporarily turned on by hand. The Dimmer creates a Comparator output approximate to its brightness, increasing and decreasing smoothly with the Dimmer. Potentially a useful alternative to traditional ways of delaying Redstone signals.

Winch

Winches are a new Tin-based redstone component that can be held down to turn, providing a redstone signal with a strength proportional to how far it has turned. If you let go before it is fully turned, the winch will start to turn back. When it reaches the final state, it will lock and can be right-clicked to unwind.

Winches continue the similar speed mechanic from Hold Buttons and Plates when placed on Gold and Silver Blocks, instead increasing or decreasing the rate at which the Winch winds. Additionally, placing a Winch on an Iron Block will cause the Winch to lock even if you have did not wind it all the way. Placing a Winch on a Tinplate Block will force it to unwind even if you wind it all the way.

Hoop

A tin component that detects when an item or projectile goes through it, releasing a redstone signal approximate to the velocity. Fun for minigames, especially as projectiles that miss will bounce off of the sides! You can make the hoop smaller with a Tuning Fork. Some more is planned for it.

Bouncer

An interesting block crafted by adding some Slime Balls and Redstone Dust to a Block of Tin. It deflects projectiles even more powerfully than regular Tin blocks. It will also emit a short Redstone signal proportional to how close to the middle the projectile hit, just like Target blocks! And funkily enough, jumping from the top of a Bouncer block will bounce you higher than normal.

Storage Duct

Storage ducts are new storage blocks crafted with Tin Blocks and Ingots. While each duct only has 9 item slots, multiple ducts can be linked together into one unified container whose contents can be viewed and scrolled through all at once! Any number of Storage Ducts can be linked together, allowing you to have as many slots as you want.

In addition to their use in item storage, they can also prove useful in item transportation. Hoppers can collect items from any part of a duct pipeline, meaning that you can insert items into one end of the duct and then extract them instantly from the other end. As ducts can be built vertically, this can also be used to move items upwards with ease. And who knows, the block’s mechanics may end up having many uses we haven’t even thought about.

Typically, the contents of Storage Duct systems can only be accessed from either end; however, Storage Duct Hatches are a block designed to allow you to access the contents of the storage duct from any part of your system! Simply place one on a duct, and it can now be opened from the hatch! This allows you to make a Storage Duct system that spans your entire house!

Roller Door

Roller Doors function much like a garage door. They can be opened and closed by powering them with redstone or right-clicking the bottom a Tuning Fork to manually open them. When opened, all Roller Doors below the base move upwards and are stored in the base of the door. They can also be placed in all six directions, allowing for a lot of custom door designs! They also have a Roller Window variant crafted with Float Glass.

Splurter and Scatterer

These funny faces are upgrades to the dropper and dispenser respectively. They have a range respective to the signal strength and output more of their inventories at once. The splurter will drop its entire inventory on activation, whereas the scatterer will only empty one item per slot, as it’s able to shoot projectiles like a dispenser. The scatterer also shoots its contents respective to the slot, so an arrow in the top left slot would be shot at that angle.

Resistor and Refractor

Two new Redstone components whose recipes incorporate Tin. The Redstone Resistor is the inverse of the Repeater; instead of strengthening the incoming signal, they weaken it by an amount that can be modified by moving the slider on its side. It’s crafted identically to Repeaters, expect instead of Stone it uses Tin Ingots. Its design is meant to resemble a Faraday cage. While Comparators do have similiar capabilities, the Resistor has a useful compactness to it and are less useful for calculations.

The Redstone Refractor is a component crafted with Tin Ingots, Redstone Torches and a block of Amethyst. When powered by Redstone, it redirects the received signal randomly to one of its three outputs. The weight of each output can be modified by moving the corresponding torch. The weights range between 0-3, with a higher weight meaning that the signal has a higher change of exiting through that output. If the weight is set to 0, the Refractor will never choose that output.

Tinplate

Tinplate is a new item crafted from Honeycomb and Tin! Tinplate lets you wax Copper blocks, like Honeycomb, but less painfully, as 1 Honeycomb and 1 Tin Ingot gives you 16 Tinplate! It can not be used for any of Honeycomb’s other uses or recipes besides waxing.

Tinplate can also be made into a storage block that functions like Tin Blocks, deflecting projectiles, but projectiles that bounce off Tinplate will bounce twice instead of once!

Ricochet Arrow

Ricochet Arrows are a simple new arrow type crafted from Tin that act as expected - they ricochet off blocks until they slow down enough to stop!

Aegis

The Aegis is new Shield variant made from Tin that fully deflects projectiles as one would expect. Use it to launch Arrows, Splash Potions, Fireballs, and more back at your enemies! It has a stripe down the middle that can be dyed similar to Leather Armor.

Packing Container

Packing Containers a Tin-based storage item, similar to Bundles but instead of holding multiple items, they can hold up to 8 stacks of a single item type. This means they can hold up to 512 of most items, or 128 of items like Ender Pearls! Packing Containers with items in them will automatically fill when picking up more of that same item. They can also be dyed like Leather Armor to gain a colored label stripe around their base.

Grazer

Grazers are a new hostile creature found in groups deep underground. Despite their unintelligent appearance, they pack a mean punch. If they are hurt or see a player, they’ll run into the nearest wall and start ricocheting off of nearby walls with their tin-rich shell, dealing damage to anything in their path. They can be killed for a source of tin, making it renewable and accessible in small quantities earlier on. Their spawning is a migration-esque mechanic tied to your seed and Moon Phases, so they’ll only spawn in your chunks every once in a while!

Saddled Grazer

Grazers now may rarely drop a Saddled Egg, which can be placed in the world. The egg must be hatched forcefully by jumping on it, which gives you a grazer of your own! You’ll have to wait for it to grow into an adult to ride it though, because the baby’s head is too big for its body, so it sits in a puddle of its own drool, waiting to grow up…

The babies will grow into a Saddled Grazer, which as expected can be ridden to control your own Grazer. They walk pretty slow, but charging the space bar allows you to fling the Grazer forward much like they would in a cave, even dealing some damage!

Rat

Rats are finally fully implemented, and they are pesky little critters that spawn in most places underground! They can be tamed with Rotten Flesh, and multiple can be tamed at once by placing a Rotten Flesh Block. When the group finishes eating the Rotten Flesh Block, it will drop a Bone Flute, which can be used to control how Rats move in packs and from a distance!

Rats will survive any attack if they have full health, but will be left injured for a moment. Receiving another attack while injured will surely lead to death. When found underground, they will often be dirty and need to be washed off. They have five different variants: blue, gray, brown, white, and the newest variant, black!

Bone Flute

Bone Flutes can be used to make all your nearby pet Rats sit at once, move to a location, return to you, or attack a mob from a distance. Rats can latch on to enemies when attacking.

Evendeeper

What’s scarier than a Deeper? An Evendeeper! Evendeepers are a Deepslate variant of Deepers with a rocky deformed shape, replacing Creeper and Deeper spawns at Deepslate level. They have a little less health and speed, but they do not need to stop moving for their fuse to start, making them slightly more dangerous!

In addition, Peepers have different spawning rules, now spawning and in rarer small groups to serve as more of an occasional combat interaction and less of a constant threat, to be a bit more forgiving and engaging.

Cavefish

Cavefish are an ambient fish that are found in… caves! They’re pretty self-explanatory. They travel in schools and can dart around pretty fast. They drop themselves when killed, and can be eaten for a little bit of food to prevent starving when mining near aquifers. Be careful though - they have a chance to give Blindness for a bit when eaten. They can also be brewed into Potions of Blindness, which surprisingly did not exist until now!

Forge

Forges are a brand new structure that are somewhat common throughout the world, anywhere in the cave layer. They resemble large industrial furnaces and have piles of old smelting remnants left inside. Whilst this includes Suspicious Gravel with a variety of new Sherds, Trim Templates, and other goodies, it also has the particularly hazardous combination of TNT and Flint Blocks. One wrong move, and both you and the remaining loot will go out with a bang!

Vault

Vaults are new underground structures found quite rarely in the depths of the world! These are small boxes with a few randomized piles of ingots and ore blocks, making for a lot of riches to collect! A couple of chests will also be found, with a mixed pool of various loot items like more ingots, gems, golden apples, and other rare items! These structures have quite a lot of valuables, but will be hard to find due to their rarity and because they generate with almost no air/cave exposure!

Lush Mineshaft

Occasionally, Mineshafts in Lush Caves will generate with Azalea wood instead of Oak. This is just a visual change and complements the colors of the Lush Caves very nicely, and can even help you stock up on some Azalea wood!

Turquoise

A shiny new gem used for being a braggart. Although it has an ore, it doesn’t generate by conventional means, and is found more in loot, like Zirconia. It has a tiny chance to drop from copper ore. Turquoise has no functional value, and exists purely for social reasons, and to show everyone what a snob you are. It’s a bit of a work in progress right now, but it will be a scarce resource, albeit renewable in unreliable ways.

Subtle Potions

A perhaps less pretentious use for turquoise is to brew it into a potion. No more bubble particles! This makes it really good for Invisibility!

Monocle

Combine turquoise with a spyglass and you can show the world what a connoisseur you are! The monocle can be used like a spyglass or worn like a helmet - either way you’ll have a very unsubtle overlay and all who bear witness will know how exquisite your tastes are!

Caviar

Have a salmon bucket lying around? No? Well, you’d better get one quick should you want the world to know you’re a true connoisseur. Caviar can be eaten any time to provide exactly zero nutritional value, but it sure makes you look cool! Should you not feel like making the effort to use it like that, you can always display your fine palate by placing it down.

Unicorn Horn

The Unicorn Horn is crafted with Turquoise and an End Rod, and can be placed on all equine mobs to make them into a fancy Unicorn! It can also be dyed any color like leather, and it can be made emissive with glow ink!

Trim Modifiers

Turquoise can be crafted with an Armor Trim Smithing Template to create a Trim Modifier Smithing Template, which is a fancy new template that can be used at a Smithing Table to apply two new modifiers to your trimmed armor!

Using the template with Spinel creates a Faded trim, which renders the trim at 50% opacity for subtler trim designs. In this image, Sanguine has a Faded Quartz trim! Emissive trims can also be made by using the template with Glow Ink, which will give the armor a nice glow!

Both modifiers can be applied to a trim for a subtler glow, and modifiers can also be removed from trims through the Dismantling Table.

Dismantling Table

With the recent additions of smithing templates for armor trims and Netherite/Necromium, sometimes you regret the modifications you make to your armor! Dismantling Tables will allow you to undo your past armor upgrades, receiving your smithing templates & materials back for the small cost of some Spinel!

Additionally includes an off-by-default tweak to the smithing table where you may not trim a piece of armor that has already been trimmed; we recommend enabling this so that when experimenting with your look, you don’t accidentally waste a trim.

Bejeweled Anvil

Another Spinel-related workstation is the Bejeweled Anvil! Bejeweled Anvils cost no XP to use, however, they are very fragile and are destroyed immediately after use! They work great alongside Zirconia for repairing some of your more expensive gear. To craft them, surround an Anvil with Spinel in the crafting table for two Bejeweled Anvils.

Atoning Table

The Atoning Table is a more cursed version of enchanting tables. Enchanting tools at the Atoning Table costs durability instead of experience. The three levels correspond to risk and reward - choosing a riskier option will net you better enchantments but cost you more durability! Atoning costs both Spinel and Lapis. Atoning Tables have a custom UI, as well as an entirely new alphabet that is used for the text in the GUI and the letters surrounding the table!

Toolbelt

Remember Environmental’s Explorer Gear? Environmental’s “Architect’s Belt” has a spiritual successor in the form of the Toolbelt, a simpler take on the concept that works a bit better alongside existing content. The Toolbelt offers two additional block reach, with an enchantment available, Extending, that allows for up to three more, as opposed to the RPG-esque level up system. It is sold as a Master trade from Masons, and found in Stronghold Corridor and Woodland mansion chests.

Cowl

Similarly, Environmental’s “Thief’s Hood” has returned in the form of a Cowl, providing lower detection range when equipped, with a Conceal enchantment that extends that range. Incompatible with Conceal is the Obscurity enchantment, which turns the player fully invisible when crouching. It is also found in Stronghold Corridor and Woodland mansion chests.

Please note that both the Cowl and Toolbelt are still work-in-progress, and are subject to many changes, mainly loot availability and enchantments.

Copper Equipment

We’ve implemented our own take on Copper Tools & Armor, focusing on justifying their existence and place in the game with unique mechanics and visuals! They have a bulkier design than Vanilla’s, as they are now made from Copper Blocks instead of Ingots, because their main mechanic is a massive increase in durability, past all other tiers. They also now slowly oxidize when equipped/held, and can be waxed.

Besides durability, the tools retain the same stats, but their mining level is increased. Copper Armor has also had its defense buffed noticeably. To counteract this, it now lowers your movement speed to create more of a classic “tank” style gameplay. Copper Helmets also have a unique model with a functional lightning rod on top!

Copper Horn

We’ve brought back the copper horn! It looks a touch different, but functions identically to how it did in the Bedrock Edition betas that it was included in before being removed without much explanation. This also includes the two variants of base goat horn that were removed around the same time, as they were needed to craft the respective copper horns.

Tether Potions, Impact Potions, and Trail Potions

Tether potions now have some siblings! Impact potions are respective to splash potions and will only apply their effect upon breaking, whereas trail potions are respective to lingering and let you… leave a trail.

Zirconia

Named after real-world faux diamonds, Zirconia is a new prismatic gem found only as loot, or as a drop from Mimes. It can be used to repair any item as though it were the repair material, which can be particularly useful for more expensive tiers. It may also be used to duplicate music discs, although duplicates have a unique texture and mention their lack of authenticity, so originals retain their value as trophy items. Zirconia can be used as a trim material.

Copied Music Disc

Combining Zirconia with a Music Disc creates a copy of that Music Disc! It functions the same, but does not pertain the special texture. Copied Music Discs can not be copied again for more copies, you must have the original.

Ornate Glass

This fancy stained glass reflects some of the fancier stained glass window designs from churches and similar buildings. It is a special glass variant made from Zirconia, to give it some decorative use.

Cave Growths and Moschatel

Cave Growths are a new type of semi-rare plant. They can appear in most places underground, although they prefer the conditions of surface caves or, rarely, the heads of Deepers! They will only generate on stone, but are placeable on anything. There are also a few colorful but rare variants that favor particular climates, but can be found anywhere. Sometimes, a new green flower, the Moschatel, can be found among them.

False Hope

The False Hope is a light-emitting flower that can be found rarely alone in caves. It generates around a little patch of Grass underground, giving the illusion of an exit to the surface!

Sparklers

Sparklers are a new light source, similar to a torch, crafted with a Stick and Gunpowder, and create passive sparkling particles. They have to be lit manually with Flint and Steel, and lighting them a second time (or sometimes colliding with them) will cause a small, non-destructive explosion of particles. Sparklers can be dyed in all sixteen dye colors for some awesome building opportunities!

Gunpowder Block

Gunpowder blocks can also be crafted from nine Gunpowder, and create a large and destructive instant explosion of black smoke when lit! Additionally, TNT is now crafted with 2x2 Sand and Gunpowder, as opposed to 3x3.

Copper Rails, Halt Rails, and Slaughter Rails

We’re slowly but surely trying to make minecarts a bit more viable. To start with, we’ve introduced Copper Rails, which are a bit of a work in progress, but are currently just a tier below iron, although, of course, it is extremely cheap and enables getting some infrastructure set up early.

Another addition is the Halt Rail. This cheap, iron-based rail can be powered from both its east and west faces, which respectively will halt minecarts coming from the north or south side. You can power both sides to halt all minecarts. A perfect way to end a railroad or simply enforce a direction.

Spiked Rails have also been changed to damage entities solely outside of the minecart, rather than within. Although mobs do, of course, avoid rails anyway, keen minecart aficionados will be familiar with the fact that isn’t always enough. The old spiked rail functionality of hurting entities within minecarts has been moved to the new Slaughter Rail!

Frosted Glass

Joining Ornate and Float Glass is Frosted Glass! Made with Quartz and Amethyst, Frosted Glass is sort of the opposite of Tinted Glass - you can just barely see through it but it allows full light to pass through as usual!

Flint Block

A block crafted from 2x2 flint that has gravity unless attached from above. When it lands, or if another falling block grazes it, it will spark and ignite fires around it, including lighting adjacent TNT.

Placeable Coal and Charcoal

Coal and Charcoal can now be placed in-world! Up to four can be placed in one block, and they can be lit on fire with Flint and Steel. Additionally, there is also a Charcoal Block for storage, with log-like placement.

Placeable Ingots

Ingots are now placeable too, allowing you to create piles of your treasures to show off! Eight ingots can be stacked into a block and are great for building vaults for storage and display! Make sure to place your Netherite and Necromium Ingots somewhere safe and hidden!

Metal Plated Bricks

Metal Plated Bricks are a new category of decorative blockset made with their respective ingots and Deepslate. They offer a slightly more grounded and realistic palette than their storage block counterparts, along with chiseled variants featuring their alchemical symbols! Two ingots and two deepslate crafts four bricks and they can be made from copper, iron, gold, silver, and tin!

Gem Lamps

Spinel and Lapis Lazuli have already had lamps, but this has now been extended to all gems, allowing for some real nice decorative and fancy lamp options for your builds!

Rhyolite

Rhyolite is a new stone type found in lava lakes! The surrounding stone is replaced and magma blocks are mixed in to give these lava lakes some more flair and some use. Rhyolite has a full blockset of polished and brick variants, as well as a bonus set of emissive magmatic variants, made with magma blocks and Rhyolite. When lava pours onto a bubble column, the lava will cool into Rhyolite, therefore making Rhyolite renewable!

Sugilite Building Blocks

Sugilite’s block palette has been slightly expanded, now featuring Bricks, Pillars, and Chiseled Bricks featuring the Mime’s face!

Dripstone Building Blocks

Dripstone already has Shingles, but we have extended its blockset with a bunch of new options for builders, utilizing Dripstone’s unique color and texture that will hopefully be quite useful in builds, and maybe even be used in future structures!

Granite, Andesite, and Diorite Building Blocks

While adding additional blocks for every other stone type, we realized the only stone variants lacking were the original three, so we thought it fitting to give Granite, Andesite, and Diorite a full new palette. They each have a unique design to put them apart from other blocksets, and the new Andesite and Diorite blocks even make up the new Vault structure!

Calcite Building Blocks

Calcite has been a large set of blocks, including (but not limited to) Smooth, Polished, Brick, and Pillar variants! It somewhat matches the Tuff set but with a few differences, mainly Chiseled Calcite, which can be placed in 6 directions and can be used in tandem with Calcite Pillars!

Tuff Building Blocks

We’ve backported the Tuff blockset from 1.21, but you guys all know what those blocks look like!

Copper Building Blocks

We’ve also backported the Tricky Trials Copper blocks (Chiseled, Grates, Bulbs, Doors, and Trapdoors) to 1.20.1 and included our own takes on Copper Chains and Lanterns, now with unique textures and models!

Pottery Sherds

Exclusive to Forges are four new Pottery Sherds for making Decorated Pots. Here you’ll find Boom, Cast, Ride, and Stalker, based on TNT, Ingots, Minecarts, and Peepers respectively! They are also fully compatible with Clayworks dyed pots and pot trims feature!

Armor Trims

In addition to Pottery Sherds, the Forge also has FIVE Armor Trims! From left to right, these are Core, Forger, Immolate, Plate, and Rim. They allow for some very cool designs!

Additionally, Tin, Turquoise, Zirconia, and Exposed, Weathered, and Oxidized Copper can now be used as trims!

Paintings

This update features five new Paintings as well! One rat-themed painting designed by our artist hatsondogs, and the other four designed by our artist five!

Music Disc - Analogue

Lastly, this update contains a brand new Music Disc composed by hatsondogs, also found very rarely in Forge loot! This disc is called Analogue and it is a great theme song for Polished Up as an update!

This concludes the release notes for Caverns & Chasms: Polished Up - but the saga is not quite over yet! We will give Polished Up a bit of time to settle on 1.20.1, to prepare for any important bug fixes that need to be made. After that time passes, we will work harder than ever to port this massive mod and update to 1.21.1 and continue the future of Abnormals there!

Thank you all for your support as we’ve crafted this update, we have never been so proud to release an update and we are so excited to see what you all do with it!
