Note: in versions of the mod for Minecraft 1.15.2, Guardian and Elder Guardian loot tables are not rolled due to a bug. As of now, Biogenic Armor is unobtainable in those versions.
When a piece of Biogenic armor is worn, getting hit by a melee attack will inflict the attacker with Slowness I. Wearing 2 or more pieces of Biogenic armor will increase the level of Slowness to Slowness II. The duration of the Slowness depends on the formula

Wearing a full set of Biogenic armor will prevent the player from losing breath underwater, along with gaining Night Vision if underwater.
Biogenic Armor can be obtained as a drop from the following mobs:
