Transforms into a Buff-Wielding Breaker at 1st and 5th Advancement

• Best Efficiency at 1st Advancement: Unlocks enhanced skill combos, and increases damage and critical hit damage for his Light attribute allies.
• 5th Advancement: Grants a significant boost to the team's critical damage and QTE skill damage.
• Go Gunhee's base version is obtainable as a check-in reward, so it's advisable to aim for his 1st advancement.
• If you miss drawing Go Gunhee, Baek Yoonho remains a strong alternative at the base level, especially if you have already invested in him. In this case, focus on advancing Go Gunhee in the future.

1st Advancement (Recommended):

Q Skill: Instantly triggers a core attack with added enhancement effects.

E Skill: Grants the entire team the Will of Brilliant Light buff

Will of Brilliant Light increases Light attribute damage and critical damage proportionate to the number of Light attribute allies, adding a powerful support element to Go Gunhee's role.

2nd Advancement: Increases Break effectiveness by 20%.

3rd Advancement:

Deals almighty Break damage when using Supernova, and enhances the Ruler’s Aura.

This advancement compensates for Go Gunhee's initially weaker Break performance compared to Baek Yoonho and improves his survivability.

4th Advancement: Increases defense by 12%.

5th Advancement:

Increases Supernova damage against enemies with a Break gauge.

When the Supernova hits an enemy without a Break gauge, it grants the Will of Fragment buff to teammates, boosting critical hit damage by 30% and QTE skill damage by 150%, greatly enhancing overall team firepower.
