| Review | |||||||||
| - One of the few Heroes with Death Immunity - Excels in the Dark Particle Dungeon, including inflicting Bleed - Highly effective in Sunday Castle Rush Kris - Excellent at All-Target Healing and Barrier creation when HP falls below 50% - Defense Reduction at 2 Transcendence and Single-Target Attack Damage UP at 6 Transcendence are also useful | |||||||||
Superior Alternative to Leo
While her performance is very similar to Leo, another Rare Hero with Death Immunity, Xiao is superior due to her ability to generate Barrier, recover HP, and boost single-target attack damage. She should be prioritized in situations where Death Immunity is required.
