Release6.2
A dragon born from M's pen who has come down to the human world, Durin is one of the most flexible off-field Pyro units in the game. His Skill lets him choose between two forms: the Dragon of White Flame shreds RES for Burning, Overloaded, Swirl and Crystallize teams, while the Dragon of Dark Decay turns him into an off-field carry built around his own Melts and Vaporizes. As a Hexerei character, he shines next to Nicole and the other witches.

Guide
How to play
How he works
- Binary Form: Convergence and Division (Skill) grants Essential Transmutation for 6s. Press Skill again to enter Confirmation of Purity (Light), or Normal Attack to enter Denial of Darkness (Dark). Entering either state in combat refunds a large amount of Energy (once every 6s).
- His Burst depends on the state. Principle of Purity: As the Light Shifts summons the Dragon of White Flame, which follows the active character and hits all nearby enemies. Principle of Darkness: As the Stars Smolder summons the Dragon of Dark Decay, which hits a single enemy harder. Both last 20s on an 18s cooldown and apply Pyro off-field.
- Light Manifest of the Divine Calculus: White Flame reduces Pyro RES and the RES of the other element by 20% after Burning, Overloaded, Pyro Swirl or Pyro Crystallize; Dark Decay gives Durin +40% Vaporize and Melt DMG. Hexerei: Secret Rite (two Hexerei characters in the team) boosts both effects by 75%.
- Chaos Formed Like the Night: the first 10 dragon attacks after each Burst deal up to 75% more DMG based on his ATK (maxed at 2,500 ATK).
Rotation
- White Flame (support): E → E → Q, then swap.
- Dark Decay (DPS): E → N1 → Q, then swap. From the second rotation, E → Q → N1 saves a bit of field time.
His dragons use Durin's current stats on every hit, so buffs that only affect the active character do not reach them while he is off-field.
Strengths
- Off-field unit that works as a Sub-DPS support or as an off-field carry
- Reliable off-field Pyro application with a 20s Burst on an 18s cooldown
- Easy access to RES shred for Burning, Overloaded, Swirl and Crystallize teams
- Fits a huge number of teams, especially with other Hexerei characters
Weaknesses
- Trades ceiling for flexibility: rarely the best choice in the strongest teams
- Poor support for Vaporize or Melt carries, since his Pyro competes with theirs
- Dark Decay teams lean heavily on Nicole to reach their best damage
- Needs a fair amount of Energy Recharge as the only Pyro unit
