Best Teams

  1. HP-scaling DPS with Sunday for turn advance, a buffer like Robin, and Huohuo for energy and HP.
  2. DEF-shred carry comps that exploit his team-wide damage taken increase.

Kit Overview

  • Skill: consumes HP to deal Fire damage that scales with his Max HP.

  • Talent/role: HP-based Fire Nihility hypercarry whose Ultimate buffs the whole team's damage.
