Varka functions as a Main DPS built around his dual-wielding kit, dealing a constant mix of Anemo and infused Elemental DMG through rapid Normal Attacks, a ground-slam Special Elemental Skill, and a Cross Slash via Charged Attack.

As a Hexerei character, pairing him with another Hexerei teammate unlocks his Hexerei: Secret Rite passive, which significantly reduces his Special Elemental Skill cooldown and greatly boosts his CRIT DMG — effectively doubling his damage output when in the right team.

For artifacts, A Day Carved From Rising Winds is his best-in-slot, and its 4-piece bonus grants a free 20% CRIT Rate boost, which means you can shift your focus heavily toward stacking CRIT DMG instead.

Aim for 65–80% CRIT Rate and as much CRIT DMG as possible, with 200%+ being the ideal target. On top of that, don't neglect ATK — hitting the 2,500 to 3,000 ATK range is key to maximizing his overall damage output.
