Absorption is a Status Effect that will impact a Player's Health bar in a positive manner by adding "extra hearts" in addition to a player's typical 10x . These Hearts appear in a yellow color as opposed to the typical red. Once enough damage has been taken by a player to deplete an absorption heart (or after two minutes pass), the extra hearts will disappear from the user's health bar permanently.
The number of "extra hearts" that appear is level*2.
Like most status effects, it can be removed by drinking Milk.
