Wither (effect)

Wither is a status effect that inflicts damage over time. Unlike Poison, it can kill undead.

Damage
The amount of damage inflicted to the affected entity is shown in the table below: The player's hearts turn black ( on hardcore mode), making it harder, but still possible for the player to see their health. Amplifiers outside the range 0–31 (corresponding to levels 1–32) are used modulo 32.
 * Due to damage immunity, the effective rate is 10 ticks ( × 1 per second) at levels 4 and up.

Immune mobs
No mobs are immune to wither, though witches are highly resistant to it.
