Unheroic Feats

Concept: “When getting better, if not using an optional class, you may instead gain a feat.”
Content: Abilities that add versatility for classless characters (and more motivation to play them)
Writing: The descriptions incentivize adoption as much as the mechanics
Art/design: More conservative graphic design than the core book but with plenty of gore and rottenness in the illustrations
Usability: Clearly and linearly laid out
