Kayron Overview & Build Tips
Kayron is a 5★ Psionic combatant in Chaos Zero: Nightmare with the Void attribute. As a member of the Wanderer faction, he carries a mysterious past and yearns for peace, haunted by lost memories. His core mechanic centers on Futility — a 1-cost status card that, when exhausted, fuels his high-damage attacks. Through his upgrade Oath of Vanity and various Epiphanies, he converts Futility into powerful offensive—or even healing—cards.
Kayron’s Manifest Ego further enhances this loop by granting additional Futility generation, stronger AoE burst via Rift of Nothingness, and scaling buffs tied to his exhausted Futility stacks. He thrives in longer battles where he can ramp up his deck, making him a great pick for captains who enjoy high-risk, high-reward DPS and complex resource management.
