Truffle

The Truffle is a Hardmode NPC that sells the Autohammer, a crafting station necessary for crafting Shroomite Bars, along with other various mushroom-themed items. To get the Truffle to move in, there must be a vacant House in (or near) a surface Mushroom Biome during Hardmode. Surface Mushroom biomes must be created manually by a player, and do not generate naturally. 100 blocks of Mushroom Grass and Mushroom Plants are required.

When threatened by enemies, the Truffle will release mushroom spores, which hover in air and deal damage.

Achievement
It Can Talk?! is the achievement you earn for successfully having the Truffle move into your world.
