The Decrepit Skeleton is a hostile mob added by Born in Chaos. It is a melee-only undead that walks on the ground, targets players, and lives in dim and dark areas across the Overworld. Its 15 health and 3 attack damage make it a moderate threat on its own, but it usually appears in groups with other undead, so it is worth dealing with early.

It spawns in many overworld biomes wherever light is low, such as at night or underground. It also appears in the Dark Tower structures, and it can be produced by two other Born in Chaos sources described below.

Spawning

The Decrepit Skeleton spawns naturally in low light. Its spawn position must have a light level of 4 or lower if the block above it can see the sky, and a light level of 0 if it cannot. It does not spawn in the Deep Dark or mushroom fields biomes. Natural spawning is controlled by the decrepitSkeletonSpawn gamerule, which is on by default. Each natural spawn is a single mob. The biomes where it can appear are listed in the table below.

Born in Chaos structures are placed about 30% closer together in this pack, which makes the mob more common near them. It is placed inside the Dark Tower variants for forest, plains and taiga: Dark Tower Forest, Dark Tower Plain and Dark Tower Taiga.

Two other sources can produce it:

  • The Undead Summonundead effect runs a procedure every tick while it is active. On each run, a 30% roll can summon a Decrepit Skeleton 2.5 blocks from the affected entity, provided the space there is open. The effect's other undead are chosen by later rolls in the same procedure.
  • A Transmuting Elixir used on a Decrepit Skeleton replaces it with a Skeleton Thrasher at the same position.

The Decrepit Skeleton Spawn Egg can also be used to place one. It stacks to 64.

Behavior

The Decrepit Skeleton has 15 health (7.5 hearts), 0 armor, and a melee attack of 3 damage (1.5 hearts) with a knockback of 0.1. Its movement speed is 0.23, which is the same as a zombie. It is 0.6 blocks wide and 1.9 blocks tall. It gives 5 experience when killed. It attacks only in melee and never shoots.

Its AI works as follows:

  • Targeting: It attacks the nearest player, without needing line of sight. If another mob hurts it, it retaliates against that mob. It does not alert other mobs when it does this.
  • Melee: It closes in at walking speed 1.0 and attacks when it is in reach and has line of sight to its target.
  • Avoidance: When a wolf or a Dread Hound comes within 6 blocks, it retreats from it at speed 1.0. This includes tamed wolves.
  • Shade: In clear weather, meaning not raining and not thundering, it uses the vanilla shade-seeking behaviour and tries to stay out of direct sunlight.
  • Sunlight: On a day with no rain or thunder, if the block above it can see the sky and it is not in water, it is set on fire for 5 seconds. It is never set on fire while it is in water or rain, and rain or water puts out an existing fire.
  • Drowning: It takes no damage from drowning.

Drops

The loot table makes one selection per kill. Bone has a weight of 100 and a Shattered Skull has a weight of 10, so the Shattered Skull drops on about 9% of kills. The bone entry gives 0 to 2 bones, and Looting can increase that count. The exact values are in the table below.

ItemAmountConditions
Bonex0.0-2.0 +looting bonus
Shattered Skullx1.0-1.0

Tips

  • Fight it in the open at night, when it is most likely to appear. Do not let it reach you with other undead, because a group of them is more dangerous than the single mob.
  • Use a wolf to push it away. Its retreat from wolves means a tamed wolf can keep it off you while you deal damage.
  • Let the sun help you. A Decrepit Skeleton that stays in direct sunlight burns, so you can force it into shade or water to stop it. Standing in water or rain puts out the fire.
  • Keep the gamerule decrepitSkeletonSpawn on if you want the mob in the world. Turn it off if you do not want natural spawns.
  • Carry Looting to get more bone and a better chance at the Shattered Skull.
