The Skeleton Thrasher is a hostile mob added by Born in Chaos. It is a melee-only skeleton with 50 health (25 hearts) and 10 armour, and it stuns players it hits. It is one of the pack's common underground and night-time hostiles, and it is also placed in the Dark Tower structure in forest, plains and taiga biomes in a persistent form that never despawns.

Spawning

Skeleton Thrasher is a monster-category mob that spawns naturally in the Overworld. Its spawn placement is controlled by a custom rule rather than vanilla light rules alone:

• Light and sky access: if the block above the spawn position can see the sky, the light level must be 4 or lower. If it cannot see the sky, the light level must be 0. In practice this means it appears in dark caves at any time and on the surface after dark.
• Excluded biomes: it does not spawn in Deep Dark or Mushroom Fields, although the spawn list includes Deep Dark.
• Dimension: it spawns only in the Overworld, in biomes tagged as Overworld biomes (plus the Terralith biome tag and Soul Sand Valley).
• Gamerule: natural spawning is controlled by the skeletonThrasherSpawn gamerule, which is on by default.

Its natural spawn weight is 4 with a group size of 1 (it spawns alone). It can appear in about 283 biomes, including caves, oceans, rivers, plains and forests. The full list is in the table below. Pack-wide, Born in Chaos spawn weights were halved to limit crowding of vanilla monsters.

The non-persistent mob is not placed by structures. The persistent variant is placed in Dark Tower structures (see the Variants section below).

Behavior

The Skeleton Thrasher uses a melee-only AI with the following behaviour:

• Targeting: it actively targets players within 14 blocks of it (its follow range). It also fights back against whatever hits it, including other mobs.
• Attack: its melee attack deals 8 damage (4 hearts) and has a reach of roughly 1.7 blocks. Its attack knockback is 4.4, and it has full knockback resistance (1.0), so it cannot be knocked back by normal hits.
• Movement: it moves at a speed of 0.21 and can step up 0.6 blocks. It wanders when it has no target.
• Sun avoidance: it avoids direct sunlight only while it is raining. Outside rain it does not seek shade.
• Stun: when it hits a player or other mob that is not blocking, the target gains the Stun effect for 25 ticks (1.25 seconds). Blocking with a shield prevents the stun.
• Damage response: when a player or other mob hits it, it gains Resistance IV for 20 ticks (1 second) and Slowness I for 10 ticks (half a second). This applies only if it has at least 5 health, is not already resistant, is not on fire, is not inside a wall, and is not standing on a magma block. Drowning damage does not trigger it.
• Animation: its block animation plays on a scoreboard condition that the code only partly traces. Its attack animation plays on every swing.

The Skeleton Thrasher has 50 health, 10 armour and 0 armour toughness. It awards 24 experience points when killed.

Drops

Skeleton Thrasher drops Bone, Piece of Dark Metal, Pile of Dark Metal, Skullbreaker Hammer, Shield and Shattered Skull. The standard drops are listed below. Looting increases the Piece of Dark Metal and Pile of Dark Metal counts.

For the main drop pool, the four item entries are weighted 100, 10, 1 and 30, which gives roughly these chances for one roll:

Bone is always dropped (3 to 5). Shattered Skull is a separate roll that gives 0 or 1, so it drops half the time. The generated table below gives the full loot table, including the persistent variant:

Skeleton Thrasher

Item	Amount	Conditions
Bone	x3.0-5.0
Piece of Dark Metal	x4.0-7.0 +looting bonus
Pile of Dark Metal	x1.0-1.0 +looting bonus
Skullbreaker Hammer	x1.0-1.0
Shield	x1.0-1.0
Shattered Skull	x0.0-1.0

Skeleton Thrasher (persistent)

Item	Amount	Conditions
Bone	x2.0-4.0
Piece of Dark Metal	x4.0-7.0
Pile of Dark Metal	x1.0-1.0
Skullbreaker Hammer	x1.0-1.0
Shield	x1.0-1.0
Shattered Skull	x1.0-1.0

Dark Metal pieces are the material for the Dark Metal armour set.

Variants

The mod adds two Skeleton Thrasher entities and two spawn eggs (one per entity).

• Skeleton Thrasher (skeleton_thrasher): the natural spawn. It has 8 attack damage, 10 armour and a 24 experience reward. It can despawn like other natural monsters.
• Skeleton Thrasher (persistent) (skeleton_thrasher_not_despawn): the Dark Tower variant. It has the same health, damage and speed, but 8 armour instead of 10. It sets persistence on spawn, so it never despawns. It is not in the natural spawn list and appears only in Dark Tower structures or where spawned by a spawn egg. It drops a slightly different loot table, with more Bone and a guaranteed Shattered Skull.

Both variants use the same stun and damage-response logic described above.

Tips

• Blocking with a shield prevents the stun, so a shield is the most direct counter to its melee.
• Because it spawns in low light, lighting up caves and the area around a base reduces how often it appears there.
• With 50 health and 10 armour, it takes a while to kill with weak weapons. Its Resistance IV response lasts 1 second after each hit it takes, so attacks landed during that second deal reduced damage.
• The persistent variant in a Dark Tower stays in place, so it can be fought again for its drops.
