Rot Damage

Rot Damage
Rot Damage is a hidden statistic that affects your maximum health by lowering it, granting you fewer and fewer maximum hearts. It slowly heals over time naturally, and if you die all Rot Damage is removed. While not fatal itself, Rot Damage can reduce your maximum health to half a heart, which spells almost guaranteed death when taking damage in combat. Rot Damage can be inflicted upon a player in a few ways:
 * Zombies have a small chance to inflict one whole point (a whole heart) of it every time they strike a player.
 * Players in a mushroom island biome will slowly suffer, receiving half a point (1/2 heart) of Rot Damage periodically. The chance of this happening is low and random, but it is not impossible for a string of very bad luck to cause the player to fail several checks, and thus be afflicted with several points of Rot Damage very quickly.
