4★ Cassius — Introduction
Character Introduction
Cassius (4★ Instinct · Controller) is a versatile support combatant in Chaos Zero Nightmare whose kit centers on Quest mechanics, card draw, and deck manipulation. He uses unique tools like Pop Eyed Popper to initiate one of four Quests and relies on cards such as Devil Dice, Shuffle, Joker, and Dice Trick to shape his hand, complete Quests, and generate powerful Quest Cards as rewards. Completing Quests repeatedly fuels a variety of effects — including draw, buffs, healing, or damage — making Cassius a universal support who enhances consistency and combo setup for his team.
His Ego Skill, Death Trick, creates two Quest Cards and applies Morale Down to all enemies for a turn, providing both defensive utility and additional Quest triggers. Cassius excels at searching specific cards with Joker, cycling the deck with Shuffle, and orchestrating repeated Quest completions to control tempo and ramp up team performance. Well-built Quest loops not only smooth out draws but also enable strong Morale buffs (via Potentials) and strategic advantages in extended engagements, especially when paired with teammates who generate low-cost cards or benefit from frequent Quest rewards.
