The Oni

Once feared by mortals, these powerful shapeshifters can change form, turn invisible, and survive almost anything. As they grow in power, they choose whether to become tougher, strengthen existing abilities, or learn new tricks such as possessing others, devouring souls, and smashing through obstacles. The game includes an oni playbook with 20 advanced moves, thematic weapons and armor, dungeon gear, magic items, optional rules, a variant core move, and five additional moves.
