Rei Overview & Build Tips
Rei is a 4★ Controller combatant with the Void attribute, aligned with the Terrascion faction. She specializes in powerful, conditional buffs: for example, her card Strike of Darkness grants +100% basic attack damage for one turn, while Resonating Darkness boosts damage of 1-cost cards. She also brings deck-cycling utility via her 0-cost Snack Time card, which exhausts cards from her hand to heal and draw.
Her Ego Skill “Final Shadow” delivers 300% damage and restores +1 AP, giving her burst + resource flexibility. Thanks to her mix of buffing, card draw, and AP generation, Rei excels in both pure support and sub-DPS roles, especially in teams focused on maximizing low-cost card plays.
