It consists of a Fungus Cap, Fungus Guard and Fungus Leggings.
The Fungus Cap gives 8 defense, 8% increased throwing damage, 33% chance not to consume thrown items, and increases maximum Technique Points by 1; the Fungus Guard gives 12 defense, 12% increased throwing damage, and 5% increased throwing speed; and the Fungus Leggings gives 10 defense, 10% increased throwing damage, and 5% increased throwing critical strike chance.
A full set provides a total of 30 defense, 30% increased throwing damage, 5% increased throwing speed, 5% increased throwing critical strike chance, 33% chance not to consume thrown items, and increases maximum Technique Points by 1. Its set bonus makes attacks dealt against enemies afflicted with the Fungal Growthdebuff deal 10% more damage and provide the Mycelium Veinsbuff to the wearer, increasing throwing speed by 10%.
The Fungus armor's set bonus makes it primarily useful when using Fungal Poppers or Morel Grenades, both also crafted with Cerulean Morels, as they are the only throwing weapons that can inflict Fungal Growth. Spore Coating will make all throwing weapons inflict Fungal Growth, removing the limited usefulness of the armor's set bonus.
The minions summoned by the Mushymen Staff also inflict Fungal Growth, allowing the player to inflict the debuff without using any consumables, albeit less consistently against larger groups of enemies.
