Ice Shuriken Zone DPS. DEF is an offensive stat — auto-attacks deal (200% ATK + 200% DEF). Giant Shuriken zone at 60x ice scaling is the highest DPS source. Multi-Shuriken bursts every 5 autos.
Skill: Thousand Blade Wave
Auto-attack upgraded to shuriken: deals (200% ATK + 200% DEF) physical DMG + 200% ice DMG (20x ice scaling).
Shunsui's auto-attacks uniquely scale with both ATK and DEF, making him one of the few heroes who directly benefits from defensive stats offensively. The ice component adds elemental damage on top of the physical base.
