Health Boost

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

Effect
Identical to Absorption, except added hearts can be healed. Added hearts initially appear as damaged until healed. Negative levels reduce base health, however the entity's actual health is not decreased to the new maximum until damaged or healed.

Immune mobs
Boss mobs are unaffected.
