Lava

Lava is a light-emitting fluid that causes fire damage, mostly found in the lower reaches of the Overworld and the Nether.

Obtaining

Lava can be collected by using a bucket on a lava source block or a full lava cauldron, converting the bucket to a lava bucket. Lava may be obtained renewably from cauldrons, as pointed dripstone with a lava source above it can slowly fill a cauldron with lava (if in the Nether, the source of lava isn't necessary). , lava does not have a direct item form, but it may be obtained as an item via inventory editing or add-ons.

Natural generation

During world generation, lava replaces air blocks generated in caves and canyons between Y=-55 and Y=-63. Aquifers are sometimes filled with lava below Y=0. Lava does not replace air blocks inside mineshafts, monster rooms, amethyst geodes, or strongholds. Lava can also occur as lava flows from a single spring block, pouring down walls into pools. The spring block can be on the side of a cave, ravine, mineshaft, or stone cliff above ground. Lava also generates as small lava lakes, which can be found above Y=0 within any biome. Two blocks of lava can also be found in plains, snowy plains, and desert village weaponsmith buildings, or one source in savanna village weaponsmith buildings. Fifteen blocks of lava can be found in the End portal room of a stronghold: 3 along each side wall, and 9 below the portal frame. Lava also generates in woodland mansions: two blocks of lava generate in the "forge room", and 25 blocks of lava generate in a secret "lava room". In the Nether, lava is more common than water is in the Overworld. Seas of lava occur, with sea level at y-level 32, about a quarter of the total height of the Nether (as the usable space in the Nether is 128 blocks tall). They can extend down to about y-level 19-22. Lava also randomly appears in single blocks inside netherrack formations. There are also large pockets of lava generated under y=19 and can reach all the way down to bedrock level. These pockets are generally over 12 blocks in height and often connect to a large lava lake on y=32; the size of these pockets in 1.18 can range from the size of a singular pre-1.18 ravine to multiple ravines combined. Lava generates as delta shapes, which can be found commonly in the basalt deltas biome. Lava is also generated as a single source in well rooms in Nether fortresses. Lava also generates in ruined portals and bastion remnants.

Renewability

If there is a lava source above a pointed dripstone stalactite, there is a (~5.9%) chance for it to completely fill an empty cauldron within 10 blocks under the tip with lava after a random tick. This lava can then be scooped with a bucket, making it a renewable resource.

Post-generation

Unlike water source blocks, new lava source blocks cannot be created in a space by two or more adjacent source blocks. However , if the game rule is set to , new lava source blocks can form in a similar way to water source blocks.

Burning

Most entities take damage every tick (although damage immunity reduces this to once every half-second) while in contact with lava, and are set on fire. An entity or player in lava also has its set to 300, setting it on fire for 15 seconds. This timer is reset to 300 every tick that the victim spends in lava, so it starts counting down once the victim leaves the lava. Once the victim does exit the lava source, it burns for just under 15 seconds, taking fire damage 14 times. This is due to the fact that for the first tick outside of lava, its decreases to 299, and entities take fire damage when is a multiple of 20 and greater than 0. If the victim touches water or rain, the fire is extinguished, but the lava continues to damage them directly. In addition, a dense fog effect is applied for players under lava to obscure vision. This can be slightly mitigated via the Fire Resistance effect. In Spectator mode, the fog effect is removed and players can see through lava. , a player with the Fire Resistance effect or a total Fire Protection of 7 or higher does not catch fire. Most of the Nether mobs (blazes, ghasts, magma cubes, striders, wither skeletons, zoglins, and zombified piglins), agents, NPCs, vexes, ender dragons, shulkers, wardens, withers, and players or mobs affected by the Fire Resistance effect are not damaged when touching lava. The embers or fireballs that fly out of lava are purely decorative and do not cause fires or damage to entities. When rain falls on lava, the black ember particles appear more frequently. A player in lava lasts a few seconds before dying:
