Instant Damage

Instant Damage is an instant status effect that decreases health for living mobs and heals the undead.

Effect
Instantly inflicts damage of × 2level. Undead mobs (including the wither) are healed as if with Instant Health instead. Death is reported as " was killed by magic". If the effect is forced to last longer than 1 tick, it damages entities every tick (with the exception of lingering potions, which inflict damage every second). Levels 30–32 provide no damage. Amplifiers outside the range 0–31 (corresponding to levels 1–32) are used modulo 32.

Immune mobs
The ender dragon is immune to Instant Damage. Witches are 85% resistant to Instant Damage. Endermen are immune to Instant Damage from splash potions, lingering potions and tipped arrows, but not from commands.
