Regeneration

Regeneration is a status effect that restores a player's (or mob's) health over time without interference from Hunger.

Effect[]

The amount of health healed over time is shown in the table below:

Level	Ticks per	per second
1	50	0.4 × 0.2
2	25	0.8 × 0.4
3	12	1.67 × 0.835
4	6	3.33 × 1.665
5	3	6.67 × 3.335
6+	1	20 × 10

Amplifiers outside the range 0–31 (corresponding to levels 1–32) are used modulo 32, making level 33 the same as level 1, etc.
