4★ Rei — Introduction
Character Introduction
Rei (4★ Void · Controller) is a support combatant in Chaos Zero Nightmare whose kit focuses on damage buffs, deck thinning, and conditional enhancements that amplify allies’ Attack Cards. Her base cards include Dark Blade for basic damage, Material Regeneration for healing, and Strike of Darkness, which boosts Basic Attack damage for a turn. Skills such as Dark Condensation and Resonating Darkness further buff specific Attack types, while Snack Time provides targeted draw and deck thinning by exhausting unwanted cards. These tools make Rei a potent buffer who increases team damage and improves consistency through controlled card flow.
Her Ego Skill, Final Shadow, deals high single-target damage and restores 1 AP, giving both offensive utility and momentum for subsequent plays. Rei’s buffs are often conditional and temporary — for example boosting damage for certain card costs or types — meaning she shines brightest in combo-centric teams that can capitalize on her one-turn enhancements. With careful deck management and strategic timing, Rei elevates both damage output and resource economy for her allies.
