Archetypes of Yuggoth
This fantasy roleplaying supplement introduces five character archetypes inspired by the Mi-Go, alien fungal creatures known for harvesting and preserving living brains. The options include an alchemist who transforms into a fungal being, an arcanist who stores spells in captured brains, a hunter with a Mi-Go companion, a rogue focused on fleshwarping, and a witch who uses brain-based magic and themed hexes. A bonus cleric domain supports characters devoted to the strange religion of the Mi-Go.
