In short: Durin is a Pyro sub DPS who deals almost all his damage through the off-field dragon from his Burst. He has two forms: the white one supports the team and shreds resistance, the dark one boosts his own Vaporize and Melt. The dragon's damage scales with ATK, so the build is ATK and crit.

How he plays: Binary Form: Convergence and Division starts Essential Transmutation. Pressing the Skill again enters Confirmation of Purity (white form), a Normal Attack enters Denial of Darkness (dark form). His Burst depends on the form: the Dragon of White Flame deals AoE damage, the Dragon of Dark Decay hits a single target. Both follow the active character.

Forms: with the white dragon, when the team triggers Burning, Overloaded, Pyro Swirl or Pyro Crystallize, the enemy's Pyro RES and the RES of the other element in the reaction drop by 20%. With the dark dragon, Durin's Vaporize and Melt deal 40% more damage. With another Hexerei character, both effects and his signature sword get much stronger.

Stats: ATK 2000+, ideally up to 2500: his passive gives the dragon +3% damage per 100 ATK, up to +75%. Crit Rate 60–70%, Crit DMG 200%+. Energy Recharge 110–140% if he's the only Pyro.

Partners: in white form — Overloaded with Arlecchino and Fischl, Burning with Kinich and Emilie, Anemo teams with Venti or Varka. In dark form — Melt with Lohen and Citlali, or Vaporize with Xingqiu. Nicole, Venti and Varka provide Hexerei.

Constellations: C1 is the most valuable: after his Burst, allies get bonus damage based on ATK in white form, while in dark form Durin's own Burst hits harder. C2 gives the team +50% Pyro and reaction-element damage, C4 +40% Burst damage, C6 DEF ignore.

Weaknesses: much of his damage and RES shred only unlocks with Hexerei. Almost all of his damage comes from his Burst, so without energy Durin is useless.

How we calculated

The team comes from the open gcsim simulation database — the one closest to the teams in this guide. Only this character was changed: constellation and weapon. Teammates, artifact sets and rotation stay as in the original simulation; the whole team's substats are optimized to KQM standards separately for each weapon. C0 with Wolf-Fang: 114,885 damage per second.

The gain depends on the team and investment: treat it as a guideline, not an exact number for your account. Original simulation · gcsim 4eda9fc, 2026-10-17
