Fatal Poison

Fatal Poison inflicts damage to entities over time, and can kill.

Effect
The amount of damage inflicted to the affected entity is shown in the table below: The player's hearts turn yellow-green ( on hardcore mode). Damage is suppressed while the player or mob is already at health, but can resume if healing occurs before the effect expires. Amplifiers outside the range 0–31 (corresponding to levels 1–32) are treated modulo 32 (as though reduced by 32 until they are within the range, or alternatively as the remainder from division by 32, i.e. 33 will be treated as 1.)
 * Due to damage immunity, the effective rate is 12 ticks ( × 0.8 per second) at levels 3 and 4 and 10 ticks ( × 1 per second) at level 5.

Immune mobs
Undead mobs, spiders and cave spiders are unaffected by this status effect.
