Health Boost

Sources	None
Particle	#F87D23 (orange)
Type	Positive

Health Boost is an unused status effect that increases a player's (or mob's) maximum health.

Effect

Adds 4 maximum health per level. Unlike Absorption, the added hearts are empty at first, but can be healed through the usual methods (such as natural regeneration and the Regeneration and Instant Health effects).

When the effect ends, any extra health is lost.

Immune mobs

Boss mobs are unaffected.

Notes

Actual health may be above the base value after the effect ends and are not capped, unless the entity is healed. Extra hearts of a mounted mob can be seen while riding it.

Trivia

The maximum health the player can achieve using Health Boost and Absorption is 2068 × 1034.
- A player who gets max health using the method above, and then adds Regeneration with the level of 255 while healing to 1034 hearts, sees the view jolt, even in Creative mode^[verify], as if taking damage. This also happens when the effect ends.
