Fatal Poison

Fatal Poison inflicts damage to entities over time, and can kill both undead and non-undead mobs. The effect is actually named identically to Poison and is distinguished only by its ID.

Effect
The amount of damage inflicted to the affected entity is shown in the table below: The player's hearts turn yellow-green. 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
spiders and cave spiders are unaffected by this status effect.

Death message
If player killed due fatal poison effect, death message shown same text as when killed by potion of harming.
