Minecraft Ice Caves Guide: Frostbite, Icicles and Freezing

Minecraft's next cave biome is built mostly out of packed ice, the block that crafts into blue ice. Ice caves were revealed at Minecraft LIVE on September 26, 2026, and they come with icicles that drop when you light them up, ice crystals that glow at light level 4, and the frostbite: a zombie variant whose melee hits apply a brand-new Freezing status effect, and whose drops brew into the potion for it.

Mojang calls this the final game drop of 2026, and both editions have it in test builds. Bedrock Preview and Beta 26.60.29, whose changelog is dated September 30, carried it behind an experiment toggle named Drop 4 of 2026; from Preview and Beta 26.70.20 (October 13), Mojang's changelog lists the drop's features outside its Experimental Features section, and the wiki's experiments page records the toggle as removed. On Java, 26.4 Snapshot 3 on October 6 added ice caves, ice crystals, icicles, the frostbite, the Freezing effect and the ice ball, and Snapshots 4 to 8 have added more since. Mojang's post for Snapshot 7 (November 3) says its additions are the final gameplay features for the drop, so what is left is tuning and bug fixes.

Everything below is preview content. Unless a line says otherwise, the numbers come from Mojang's changelog and the Minecraft Wiki's entries for Bedrock Preview 26.60.29 as of October 2, 2026, with some later Java and Bedrock changes noted where they bear on them. Numbers can move before release, and where the sources disagree, this post says so rather than picking one.

Ice caves at a glance

How to play the ice caves before release

Both editions have it in test builds now. On Bedrock:

1. Get the test build. Mojang's changelog lists Minecraft Preview on Xbox, PlayStation, Windows and iOS, and the Beta on Android through Google Play. 26.70.20 or later has the drop without an experiment toggle.
2. Create a new world. On 26.60.29 you also had to turn on Drop 4 of 2026 in the world's Experiments settings, and per the wiki's experiments page, a Bedrock world with an experiment on cannot earn achievements and the experiment cannot be turned off once the world exists.
3. Accept the risk. Mojang's preview changelogs warn that these work-in-progress versions can be unstable, so back up or use a separate save.
4. Head for snow. The next section explains why.

On Java, Mojang's snapshot posts say to open the Minecraft Launcher and enable snapshots in the Installations tab, and warn that testing versions can corrupt your world, so back up or run them in a separate folder. 26.4 Snapshot 3 (October 6) is the first with ice caves, and its changelog lists them under New Features with no experiment involved. Snapshot 4 (October 13) added brittle ice (it generates in ice caves), Snapshot 5 (October 20) added packed ice bricks, Snapshot 6 (October 27) snow bricks and a cold sulfur cube, and Snapshot 7 (November 3) the calcite block set, the "Flurry" music disc and a decorative block Mojang only says it added "somewhere". Snapshot 8 (November 10) is mostly fixes; for this drop, it trimmed ice ball damage and made all undead mobs immune to Freezing. Mojang's testing page for this drop says it will collect each new testing moment in one place as they arrive, so that is the page to watch for what comes next.

Where ice caves generate: go to the snow, then go down

Mojang's changelog keeps it short: ice caves appear under biomes with low temperature. The wiki's generation notes fill in the rest. They tend to form at very high weirdness values, typically below snowy biomes such as ice spikes, snowy plains, snowy taigas and frozen oceans, and sometimes below less-cold biomes. Where humidity or continentalness climbs, lush caves or dripstone caves take their place instead.

That weirdness rule makes ice caves the mirror image of sulfur caves. Per the wiki, sulfur caves never border ice caves, though the two can generate near each other, usually with a river on the surface between them. So the search plan flips too. Our sulfur caves guide tells you to stand on flat ground near a swamp or desert and look for a spring; for ice caves, get to snow first and dig down from there.

Two rarer ways in: in oceans, ice caves can rarely generate above the seabed at weirdness above 1.25, and the wiki says generating above the water or on land is rarer still, needing even higher weirdness; and like other cave biomes they can leak out of cave openings and ravines. If a ravine wall in a snowy biome looks blue instead of grey, look closer.

What is actually down there

The packed ice row is the practical one. Bring Silk Touch. Packed ice drops nothing without it, and nine packed ice craft one block of blue ice, the fastest ice for a boat road. A cave whose walls are mostly packed ice is a blue-ice quarry waiting to be dug out; our transportation guide covers what that road is worth. For ores, you are mining the stone and deepslate pockets, not the ice, so the usual Y-level advice in the mining guide still decides what you find in them.

Do not count on amethyst down here. Per the wiki, packed ice is on the list of blocks an amethyst geode cannot start generating in, so geodes rarely generate in ice caves; a bug report about it (MC-312663) was closed as Works As Intended. If you came for shards, our amethyst geode guide covers where geodes do generate.

Water behaves two ways here. Per the wiki, water exposed to the sky freezes into ice, while water from underground aquifers stays liquid.

The mob list is where it gets cold. This is Bedrock's preview spawn table for the biome, from the wiki. The wiki now lists a separate Java table with different weights and group sizes, so do not assume these numbers carry over to Java.

Frostbites spawn at essentially the same weight as plain zombies (50 against 50.05) and in the same group size. Strays, which fire tipped arrows of Slowness, are in the mix too. That puts two different slowing attacks from two different mobs in the same cave, which is worth knowing before you go down without a plan for either. The zombie villagers in that table spawn as their snowy variant here, since Java Snapshot 6 and Bedrock Preview 26.70.22.

Icicles: dripstone that falls when you light it

Mojang's own description of the icicle is a "speleothem-like block similar to Dripstone and Sulfur Spikes". Like pointed dripstone, it falls and it punishes anything that lands on it, and it adds a trigger of its own: light.

Light is the rule that changes how you build. Mojang's notes say icicles only grow where there is no nearby light source and outside the Nether, and that if light levels get high enough there is a chance they drop and hit whatever is underneath, with only the base block staying put. In the Nether they break too. A falling icicle damages entities the way a falling dripstone stalactite does. So the reflex of torching up a new cave works against you here: light the room, and you are the thing standing under the ceiling.

Floor icicles are a working spike trap. Icicles cannot grow stalagmites, and the wiki says icicle stalagmites do not generate naturally, so an upward-pointing icicle is one a player put there. Mojang's changelogs for both editions say an icicle deals extra damage to entities that land on it, and the wiki gives the death message "impaled on a stalagmite". The exact amount is not confirmed: the formula on the wiki's icicle page is the one pointed dripstone stopped using in Java 1.21.5, so treat any multiplier you see quoted as unverified. Sulfur spikes skip that bonus entirely, so an icicle floor punishes a fall where a sulfur spike floor does not.

Ice crystals: light level 4 and fragile

Mojang compares the ice crystal to an amethyst cluster. It generates on top of packed ice, can be placed facing any direction, breaks if you remove the block it sits on, and gives off light. The wiki puts that light at level 4. With glow lichen absent, Mojang's notes call the crystals the only light source in ice caves; the lava in Mojang's own screenshots is the exception you will notice first.

Light 4 is dim, but it does something. Most Overworld monsters in both editions now need a block light of exactly 0 to spawn, as our mob spawning guide explains, so a crystal keeps monsters off the small patch of floor its light reaches. It will not light a cave.

Three updates since the first preview. Bedrock Preview 26.60.29 listed a known issue that crystals were smaller than intended; Mojang's notes for Preview 26.70.20 say they now render at the right size. Java Snapshot 6 and Bedrock Preview 26.70.22 gave a crystal sitting on packed ice a chance to play an ambient sound, so you may hear one before you see it. And you are not limited to the ones that generate: in the 26.4 snapshots' game data, from Snapshot 3 on, the Java wandering trader can sell 1 ice crystal for 2 emeralds and 2 icicles for 1 emerald, 5 trades each, though Mojang's Java changelog does not mention it. Bedrock now matches on the crystal: Mojang's notes for Preview 26.70.22 say wandering traders sell one ice crystal for two emeralds. That settles the earlier mismatch, when the wiki listed Bedrock at 2 crystals for 1 emerald. Any tool mines them; a pickaxe is fastest.

The frostbite: a zombie built for powder snow

At Minecraft LIVE it was "the frozen zombie variant" with no name. By the September 30 preview it was the frostbite. Mojang's summary is that it can throw ice balls, but what it really wants is to get close and hit you with melee attacks that apply Freezing.

The combat logic, per Mojang's notes and the wiki, is a range switch. A frostbite carrying ice balls throws them while it closes the distance, then swaps to melee once it is near. Per the wiki, most frostbites use the melee attack and only some spawn holding ice balls. On Bedrock, the wiki also notes that 15% of naturally spawned baby frostbites can turn into jockeys and ride another mob.

Powder snow makes them, water unmakes them

The frostbite slots into the zombie family's conversion chain:

• A zombie or husk left inside powder snow converts into a frostbite. Mojang's notes on both editions confirm the conversion but give no timer. The wiki's frostbite and damage pages first said 30 and 45 seconds and now both say 22, so treat the timer as unconfirmed.
• Leather blocks the conversion. From Java Snapshot 7, a zombie or skeleton wearing any piece of leather armor will not convert into a frostbite or a stray; Mojang's notes for Bedrock Preview 26.70.23 say the same for zombies, husks, drowned and skeletons submerged in powder snow.
• A frostbite whose head stays underwater for over 30 seconds starts converting into a zombie, per the wiki's zombie page.
• That zombie, left underwater, goes on to become a drowned. In Java the chain also runs the other way: per 26.4 Snapshot 4's changelog, a drowned in powder snow now turns into a zombie before converting into a frostbite.

The first line matters most. Frostbites are the only ice ball source the sources list, and ice balls are the only Freezing ingredient, so powder snow doubles as a frostbite converter. Turning a zombie farm into an ice ball farm is the obvious build once the drop ships (zombies wearing leather armor will not convert), but with the conversion timer unsettled and both editions still in testing, any rate quoted now would be a guess.

Freezing: powder snow as a status effect

Freezing does to you what standing in powder snow does, wherever you are: Mojang's changelog says those affected "slowly become frozen as if in Powdered Snow". The wiki spells out the powder snow numbers it borrows. You slow down gradually, to half your normal speed over 7 seconds, and once fully frozen you take damage every 2 seconds until you stop freezing: 1 point in powder snow, and 1.5 from the Freezing effect, per the wiki's freezing and damage pages. Mojang adds that it makes players shake and lowers jump height; the wiki reports the jump-height part is not working in the current preview because of a bug.

Read against those timings, a single frostbite hit is mostly a slow. Its 3 seconds of Freezing do not reach the 7-second mark where freeze damage begins. A frostbite that keeps hitting keeps the effect topped up, though, and that is how the damage arrives. On the wiki's numbers, the danger is the slow setting up the next hit.

The counter is leather. Any single piece of leather armor stops you freezing, as it already does in powder snow. Mojang's notes are careful about what it does not do: leather does not stop the effect being applied and does not remove it. The wiki's summaries disagree on whether the slowdown still applies under leather, so until that is settled, test it before you rely on it. A pair of leather boots kept for frostbite-heavy caves is cheap insurance either way, and the armor guide covers where leather fits.

Two more rules. Fire counters it: the wiki already said standing in fire or lava nullifies the effect, and since Java Snapshot 7 simply being on fire does too, the way leather does (Bedrock Preview 26.70.23's notes say being on fire stops freezing from building up until the fire goes out). And freezing damage to players can be switched off with the existing game rule (freeze_damage on Java, freezedamage on Bedrock), covered in our game rules list.

Who shrugs it off, and who takes five times the damage

The immune list has grown twice in the snapshots. These ignore Freezing now:

• Every undead mob. Mojang's Snapshot 8 changelog made all undead mobs immune to the Freezing effect on Java, and per the wiki, Bedrock Preview 26.70.24 did the same for both powder snow and the effect. That covers frostbites, zombies, husks, drowned, skeletons, strays and withers, among others. (Snapshot 4 had already made zombies, drowned and husks immune on Java.)
• Immune, per the wiki: ender dragons.
• Cannot be frozen, per the wiki: polar bears and snow golems.
• Cannot take damage, per the wiki: creakings spawned by a creaking heart.
• Protected: anything wearing leather armor, including a horse in leather horse armor, and anything on fire (above).

The other end is more interesting. Mojang's notes say mobs that are vulnerable to freezing take five times the damage. The wiki's list of mobs that take extra freezing damage is short: blazes, magma cubes and striders. That makes a splash Potion of Freezing a Nether-mob weapon on paper, and with the undead change, a wasted throw at a zombie or skeleton crowd. For the effects already in the released game, see our status effects guide.

Ice balls and the Potion of Freezing

Ice balls are the frostbite's projectile and the drop's one new brewing ingredient. Mojang's numbers in the first builds on both editions: an ice ball deals 4 damage, scaling down with its velocity, carries knockback, and breaks on impact with a block or an entity. Bedrock Preview 26.70.21's notes then say its base damage was increased to 2, which does not square with that 4, so treat the damage as unsettled. It is still moving on both editions: Mojang's Java Snapshot 8 notes say ice ball damage "has been reduced", which the wiki gives as a speed multiplier cut from 1.395 to 1.3, and per the wiki, Bedrock Preview 26.70.24 stopped player-thrown ice balls dealing critical damage. The wiki adds that it decelerates sharply, so it hits hardest up close; that it stacks to 16; and that, unlike a snowball, it deals no extra damage to blazes. The wiki lists it as a throwable item, like a snowball.

Brewing follows the standard chain from our potion brewing guide:

The durations, per the wiki's preview data, which lists only a level I potion:

The arrow row is short, but the cauldron method makes arrows cheap. On Bedrock, the wiki's tipped arrow page says a full cauldron of potion tips up to 64 arrows, against 8 per lingering potion through the crafting grid.

Snow bricks, calcite blocks and the Flurry disc

Snapshots 6 and 7 turned the drop from a biome into a builder's update too. Mojang's Snapshot 7 post says that snapshot's additions are the final gameplay features for the drop, and Bedrock got each set in the Preview listed below.

Ice caves are a calcite source in their own right, since calcite blobs sit in the walls, so the same trip that fills a shulker with packed ice can stock a calcite build. Snow bricks need snow blocks, which you craft from snowballs as usual. For the disc, an igloo with a basement is a cold-biome surface structure, so the hunt overlaps with finding an ice cave anyway; our music discs guide covers the discs already in the game and how to get them.

Sulfur cubes got a cold side as well. Snapshot 6 and Preview 26.70.22 added a cold archetype: feed a sulfur cube blue ice and, as it moves, it freezes the water below it into a disk of frosted ice, like the Frost Walker enchantment. Mojang's notes say it only does this if it starts moving while on the ground, with air above the water (Bedrock's notes say it works over water source blocks). On Java it first floated as well, but Snapshot 8 took that away so it matches the archetypes with similar properties. For how archetypes work, see our sulfur caves guide.

What else Minecraft LIVE announced

The ice caves were the near-term base-game news. The rest of the September 26 show, from Mojang's recap:

The Sift is the one to watch for the base game. During the broadcast Mojang showed a glimpse of it in Minecraft itself, with pink grass, white-canopied trees and one of its mobs, the rabbit-like creature in the shot above, which the wiki lists as the blub. Beyond that glimpse, most of what is known about the Sift comes from Dungeons II, and the wiki marks its list of the dimension's blocks as conjecture: per the wiki, only the blub has been officially named so far. The one Sift-linked block already in the base game's test builds is chiseled soulshale, which the wiki calls Sift-themed (see the table above).

What could still change before release

Preview content is a draft, though a later one now: Mojang's Snapshot 7 post says that snapshot's additions were the final gameplay features for the drop, so expect tuning rather than new content. Here is what is already visibly moving:

• Names. The frostbite went from unnamed at LIVE to named in the September 30 changelog. Other names could change too.
• Ice ball damage. Mojang's first notes on both editions say 4; Bedrock Preview 26.70.21's notes say its base damage was increased to 2; Java Snapshot 8 reduced it again.
• Freezing and jump height. Mojang says the effect lowers it; the wiki says that part is currently bugged.
• Conversion timing. Mojang has not given a powder snow timer for zombies becoming frostbites, and the wiki's figure has already changed once, from 30 or 45 seconds to 22.
• Java behaviour. Most numbers here come from Bedrock's preview, and the Java spawn table already differs. The two editions have been converging, though: the ice crystal trade (1 for 2 emeralds on both since Preview 26.70.22), undead immunity to Freezing (Java Snapshot 8, Bedrock Preview 26.70.24 per the wiki) and fire countering Freezing (Java Snapshot 7, Bedrock Preview 26.70.23) now broadly line up.
• Release date. Mojang has not announced one, and the version numbers in the table above are the wiki's.

For scale, the previous drop, Wilderness Bound, shipped on September 15 after its own run of previews and snapshots. Check the last-updated date on this page before you build around any number in it.

Quick Action Checklist

• Want it now? On Java, enable snapshots in the launcher and play 26.4 Snapshot 3 or later. On Bedrock, install Preview or Beta 26.70.20+ and make a new world; no experiment toggle is needed there. Back up first: Mojang's snapshot posts warn that testing versions can corrupt worlds.
• Find it under snow. Snowy plains, snowy taigas, frozen oceans and ice spikes are where to dig; per the wiki, they never border sulfur caves.
• Pack Silk Touch. The walls are packed ice, which drops nothing without it, and nine packed ice craft one blue ice.
• Do not torch the ceiling. Enough light can drop icicles on you; only their base block stays.
• Do not fall onto an icicle. Per Mojang, floor icicles deal extra damage to anything that lands on them; sulfur spikes do not.
• Wear one piece of leather. Per Mojang it stops you freezing from frostbite hits and Freezing potions, though it does not clear the effect.
• Keep frostbites at range where you can. Ice ball carriers throw on approach, but it is the melee hit that adds 3 seconds of Freezing.
• Keep the calcite. From Snapshot 7 it crafts into pillars, slabs, stairs, walls, polished calcite and polished calcite bricks.
• Keep the ice balls. They are the only Freezing ingredient listed: awkward potion, then gunpowder, then dragon's breath, and on Bedrock a cauldron tips up to 64 arrows.
• Recheck before you build around a number. It is a preview; ice ball damage, conversion timing and edition differences are all still open.
