Health Boost

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

Effect
Identical to Absorption, except added hearts can be healed. Added hearts will 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
Undead mobs are unaffected.
