Iseol Yu Guide
Team Attack Speed + Weakness Atk Rate buff on crits
Low damage output, limited utility
Iseol Yu is a melee DPS hero with a unique support capability through his critical hit attacks. Every time he lands a critical hit, he grants all allies the Seven Blossoms Blade buff, which increases both Weakness Attack Rate and Attack Speed by 20% for 2 seconds.
However, his individual damage output is significantly below the current meta standards. With a basic attack at 500% and critical hit attack at 800%, he falls well short of the 3800% threshold needed to be considered a competitive damage dealer. His active skill provides a self-buff but offers no team utility beyond that. In the current state of the game, where burst damage and team amplification are the keys to success, Iseol Yu struggles to find a place in end-game content.

Why Iseol Yu Stands Out
Iseol Yu's unique contribution is providing team-wide Attack Speed and Weakness Attack Rate buffs through his critical hits. This makes him one of the few heroes that can consistently boost these stats for all allies without requiring specific team compositions. However, his damage contribution is insufficient to justify a team slot in competitive content.
Recommended Synergies
Best Game Modes
- PvE — suitable for early game content where damage thresholds are lower
- Collection — not recommended for end-game PvE or PvP content
Build & Optimization
Focus on Critical Hit Rate to maximize the frequency of team buffs from Seven Blossoms Blade. Critical Hit Damage and Attack are secondary priorities to improve personal damage output. This build works across Deep Nightmare, Nightmare, Abyss Expedition, Hard Boss Challenge, and Tower of Ascension.
