Few are as deadly as the Magma Cube locking sights on you. Get seen by this red and black horror and it bounces for you relentlessly, its springy body barely concealing a molten lava core that will fill your body with hot flamy pain. Friendly hugs are not advised.

A magma cube is a hostile mob with dark red and black skin and red, orange, and yellow eyes that is found exclusively in the Nether. They are considered the Nether equivalent of slimes, with similar behaviors.

Spawning[edit]

Magma cubes spawn almost everywhere in the Nether at all light levels, but their spawn rate is higher in nether fortresses.

Magma cubes require two vertical transparent blocks[verify] (e.g., air, signs, torches) to spawn in, with an opaque block underneath. The space they spawn in must also be clear of solid obstructions and liquids.[verify] Big magma cubes require a 3×2½×3 space to spawn, small magma cubes require a 3×2×3 space, and tiny magma cubes require a 1×2×1 space (or 1×1×1 if the upper block is not opaque).[2]

Magma cubes spawn in groups of 1-4.

Drops[edit]

All but tiny-sized magma cubes have 14 chance of dropping a single magma cream. The maximum amount of magma cream is increased by 1 per level of Looting. The chance of a magma cube not dropping any magma cream can be found using the formula 3 / (Looting Level + 4). For example, Looting III gives a 37 chance of not dropping any magma cream. All other amounts have an equal chance of occurring.

Behavior[edit]

A magma cubes moves by hopping at intervals of 40 to 120 ticks (2 to 6 seconds).

A magma cube seeks out any player (or, failing that, an iron golem) within 16 blocks (spherical) distance. If it finds no target, it waits 40 to 120 ticks (2 to 6 seconds), then changes direction by a random amount up to 57.30° (1 radian) left or right, jumps, and repeat the process. If it finds a target, the delay before jumping is 13 as long (13 to 40 ticks), and the magma cube changes direction directly toward the target before jumping.

Like other Nether mobs, magma cubes cannot burn and are not slowed down or damaged by lava. Instead, it seems that they can swim upward extremely quickly in lava. They cannot be hurt from fall damage. Since Java Edition 1.13 they can swim, and don't drown in normal water (in previous versions they could not swim and would drown).

Their jump height depends on their size. Their forward speed is twice that of most other mobs. They always make a distinct sound upon jumping up and landing, but no idle sounds.

When the player kills a magma cube and the cube's size is larger than 1, it dies and spawns 2 to 4 new magma cubes half its original size, rounding down. The new magma cubes are ejected at high speed.‌[Bedrock Edition only].

Unlike most other mobs, magma cubes have no pathfinding ability, meaning that they do not avoid falling off cliffs and cannot go around walls, even when chasing a player.

Combat[edit]

Magma cubes attack players by attempting to land on top of them but can cause damage when the player touches them anywhere. This can make large cubes tricky to fight, as their jump rate is fairly random.

The health of a magma cube is size squared. The attack strength is size plus 2. The armor points is size tripled.

A magma cube can jump a distance approximate to its length times 1.5, and a height equivalent to its size in blocks. This means that a size 4 magma cube jumps four blocks in height and moves significantly quicker than a size 2 magma cube, which jumps two blocks in height, while a size 1 (tiny) cube moves at a slow rate and jumps one block in height.

When a magma cube is killed, it may split into 2 to 4 magma cubes of the smaller size, and disappear like other mobs if the smallest size is killed.

Magma cubes also have an attack speed double that of other melee-combat mobs. Mobs like Endermen and silverfish attack at a rate of one hit per second, while magma cubes attack at a rate of two hits per second. This means that a size 4 magma cube can deal six hearts of damage per second on normal difficulty, dealing three hearts every half-second.

Data values[edit]

Magma cubes have entity data associated with them that contain various properties of the mob.

  • Entity data
    • Tags common to all entities see Template:Nbt inherit/entity/template
    • Tags common to all mobs see Template:Nbt inherit/mob/template
    •  Size: The size of the magma cube. Note that this value is zero-based, so 0 is the smallest magma cube, 1 is the next larger, etc. The sizes that spawn naturally are 0, 1, and 3.
    •  wasOnGround: 1 or 0 (true/false) - true if the magma cube is touching the ground.

History[edit]

Java Edition
1.0.0Beta 1.9 PrereleaseAdded magma cubes.
“It started out as a retexturing of the Slime for the Nether - it was just going to be a Lava Slime. But then when I named it that, I felt it was a bit lazy to retexture a mob. I wanted to make it more unique. I can’t really remember how I came up with the idea to have a layered block, but it’s one of my favourite mobs now. It really intrigues me. It doesn’t stand out in any particular way - I just really like it! You can use Magma Cream [an item Magma cubes drop] to brew Fire Resistance potions.” -Jeb[1]
Beta 1.9 Prerelease 2Magma cubes were made quite rare.
RC1Magma cubes were given sounds.
1.1?Large and small magma cubes now drop magma cream.
1.3.112w18aMagma cubes did not show their animation in single player, due to singleplayer being a local server.
12w23aMagma cubes now show their animation in multiplayer.
1.814w06bMagma Cubes can now swim as a result of the update to the new AI.
Randomly change direction every so often, reducing the chance of them getting stuck at walls or corners.
Now randomly despawn over time if no player is within a 32 meter range.
Magma cube jumping mechanics have been changed. How far they jump now corresponds to the length of their size; they jump approximately 1.5 times their current length. For example, a tiny size 1 magma cube jumps very slowly, while a large size 4 magma cube jumps farther. Also, when attacking, magma cubes turn their whole body to face the player.
1.1016w20aNow spawn about twice as often in the general Nether (rate is now 2153, was 1151).
1.1116w32aThe entity ID is changed from LavaSlime to magma_cube.

Trivia[edit]

  • When a larger magma cube that has a name dies, the smaller magma cubes it spawns also have the same name.
  • A dying magma cube can still damage the player.‌[Legacy Console Edition only]
