The Supreme Bonescaller is a hostile boss mob added by Born in Chaos. It is the strongest member of the Bonescaller line. It keeps its distance and fires magic-arrow projectiles at players, calls Bone Imp minions to its side when it is hurt, and is fire immune. When its health falls to 15 or below, it is replaced by a second form, the Supreme Bonescaller (Stage 2), which has less health and fires faster.

The mob exists in three forms: the regular monster, a persistent copy that is placed in Dark Tower structures, and the Stage 2 form, which normally appears only through the transformation. The regular and persistent forms share their stats and behaviour. Stage 2 is the only form that gives experience.

Spawning

The regular form spawns naturally in the overworld, in 283 biomes, with a weight of 1 and a group size of 1 in each. It belongs to the monster category and is not tied to the time of day. Instead, it uses a light check at its position:

• If the block above it can see the sky, the block light must be 4 or lower.
• If the block above it cannot see the sky, the block light must be 0 or lower.
• It does not spawn in the deep dark or mushroom fields biomes.
• It spawns only in the overworld, in biomes tagged as overworld biomes or in Terralith biomes, and in soul sand valleys.
• The bonescallerSpawn gamerule must be enabled. It is on by default.

Because of the light check, the mob appears in dim areas, mostly at night and in shaded ground such as caves and areas under dense cover.

The persistent form spawns only in Dark Tower structures in forest, plains and taiga biomes. It is not removed when players move far away. The regular form does not have this exemption and follows the normal despawn rules for hostile mobs.

The Stage 2 form does not spawn naturally. It appears when a regular or persistent form drops to 15 health or less, or when a Stage 2 spawn egg is used.

Behavior

Ranged attacks

The mob has no melee attack goal, so all of its attacks are ranged. It targets players within its follow range of 15 blocks and retaliates against any entity that hurts it. It moves toward its target at 1.25 times its walking speed. It stops to fire once it is within 10 blocks of the target and has line of sight for at least 5 ticks. It does not fire when the target is out of sight.

Each shot is a Staff of Magic Arrows projectile with a base damage of 2.5. The regular and persistent forms fire every 45 ticks (2.25 seconds). Stage 2 fires every 35 ticks (1.75 seconds). When it has no target, the mob wanders and looks around at random.

Defensive response (regular and persistent forms)

Each time the regular or persistent form takes damage, it checks three things: whether its health is at or below its maximum health minus 5 (60 health or less of 65), whether it is not on fire, and whether it does not already have Magic Depletion. If all three checks pass, it does the following:

• It gains Resistance III for 7 seconds.
• It gains Magic Depletion for 12 seconds.
• It summons two Bone Imp minions, one 2 blocks to each side along the x axis. A minion is only summoned if that space is open, meaning it is not a solid block and is not snow.

This check runs before the mob's damage immunities are applied, so it can fire on a hit that the mob then ignores. While Magic Depletion lasts, the check cannot fire again, so the summons come at most once every 12 seconds.

Defensive response (Stage 2)

Stage 2 has the same check with a stronger reaction. Its threshold is strictly below its maximum health minus 5, which means below 55 health of 60. When it fires, it gains Resistance IV for 8 seconds, Strength II for 8 seconds, and Magic Depletion for 13 seconds. It summons three Bone Imp minions: two on the same sides as the regular form, and a third 1.5 blocks forward along the z axis.

Transformation

When the regular or persistent form has 15 health or less, it spawns a Stage 2 form at its own position with its own facing. The Stage 2 form starts at its full health of 60. The regular form is then removed. A totem-use sound plays and dark smoke particles appear. The transformation is not a death, so the regular form drops nothing. A single hit that takes it from above 15 health to 0 kills it before the transformation check runs.

Stage 2 is a separate entity with its own stats. It has 60 maximum health instead of 65. It takes arrow damage and trident damage, which the regular form does not.

Immunities

The regular and persistent forms are immune to fire damage, arrow damage, fall damage, drowning and trident damage. Stage 2 is immune to fire damage, fall damage, cactus damage and drowning. All forms are fire immune.

Death

Only Stage 2 can die through normal means. When a player kills it, the advancement described as "Kill the Supreme Bonescaller" is awarded to that player.

Drops

Stage 2 is the only form with a loot table, and its drops are listed in the table above. The regular and persistent forms have no drops of their own because they are normally replaced before they reach 0 health. Stage 2 gives 65 experience on death.

Supreme Bonescaller

No item drops.

Variants

• Supreme Bonescaller — the regular form. It has 65 maximum health, 5 armor, a movement speed of 0.2 and a follow range of 15. It spawns naturally, transforms at 15 health and gives no experience.
• Supreme Bonescaller (persistent) — the same stats and behaviour as the regular form, placed in Dark Tower structures. It does not leave when players are far away, and it gives no experience.
• Supreme Bonescaller (Stage 2) — the second form. It has 60 maximum health, a 35-tick firing interval and fewer immunities. It appears through the transformation, and it gives 65 experience.

Related items

• Supreme Measure — a weapon with an attack damage of 5000 and an attack speed of 1. It is fire resistant and has no durability limit. Its tooltip says it is only available in creative mode.
• Spawn eggs — there are three eggs: one for the regular form, one for Stage 2 and one for the persistent form.
• Staff of Magic Arrows — the regular and Stage 2 forms fire the same kind of projectile as this staff. Stage 2 can drop the staff; see the drops table for chances and counts.
• Bone Imp — the minions summoned by the boss's defensive response.

Tips

• Bows are useless against the regular and persistent forms because they are immune to arrow damage. Stage 2 takes arrow damage, so bows work against it.
• The mob fires only when it can see its target. Breaking line of sight stops its shots and gives you time to close in or retreat.
• Its defensive response summons Bone Imps whenever it is hurt below the threshold and not already under Magic Depletion. Clear the minions quickly, and avoid dealing hits while Magic Depletion is still active if you want to limit the summons.
• Because the mob is fire immune, fire damage is not a reliable weapon against it. If you want to kill the regular form before it transforms, one heavy hit that takes it from above 15 health to 0 is the only way to do so.
• The regular form spawns in dim light, so bring a light source when you go into caves and forests at night.
