Yun Jin is a Support character for Normal Attack focused characters who can deal off-field damage via her Elemental Burst. Yun Jin's Elemental Burst grants nearby party members 30 stacks of additional flat damage bonus on Normal Attacks which scales with Yun Jin's current DEF. This means that external DEF buffs like from Gorou's Elemental Skill and/or Burst doesn't provide much to Yun Jin since it only buffs active characters and not off-field ones.

Increases Elemental Skill DMG by 6~12%. After Elemental Skill hits an opponent, the character loses 3 Energy but regenerates 3~5 Energy every 2s for the next 6s. This effect can occur once every 10s. Can be triggered even when the character is not on the field.
Although the EM mainstat isn't useful for Yun Jin, the passive decreases her Energy Recharge requirements by a lot, especially at higher refinements. It can reduce her ER% reqs depending on refinement. Note that she must cast Elemental Burst first before Skill, as the passive drains 3 energy initially when Skill is cast. This weapon can be left at level 1 while still getting full effect from the passive.
