Yun Jin vs Illuga

The stage performer vs. the nomadic Geo hunter

TL;DR — Quick Pick

Pick Yun Jin if…

  • In teams centered around a single Normal Attack carry
  • When you need the C6 Attack Speed buff for faster rotations
  • If you need a low-cost Geo support who doesn't take field time

Pick Illuga if…

  • In Geo teams that need more off-field pressure and energy
  • When you can leverage his Geo constructs for resonance damage
  • Against multiple targets where his AoE outshines her single-buff focus
Verdict

Yun Jin is a better specialist for specific carries like Yoimiya. Illuga provides more general utility and personal damage to Geo-focused teams, making him a more versatile sub-DPS option.

Shared Team Members

With Yun Jin

Zhongli provides the Geo Resonance and shield necessary to protect the team while Yun Jin buffs the primary attacker. His Jade Shield's RES shred stacks with other buffs to maximize the damage of the Normal Attack carry Yun Jin is supporting.

With Illuga

Illuga benefits from Zhongli's pillars and shield, which help activate Geo Resonance and provide consistent interruption resistance. Zhongli's universal shred ensures Illuga's damage remains high against all types of enemies.
