Seeking to revive an ancient past, she is the sole being who has mastered the secrets of Yin and Yang.

DualityLuo Yi's skills can create Sigils of Yin/Yang on the battlefield. Each Sigil lasts up to 6s. Sigils of opposite attributes will trigger Yin-Yang Reaction when they are within a certain distance, dealing 365 (+20*Hero Level) (+190% Total Magic Power) Magic Damage to the marked enemies, stunning them for 0.3s, and pulling them toward each other. Each time Luo Yi applies a new Sigil to a marked enemy, she gains a 300 (+10*Hero Level) (+150% Total Magic Power) shield (up to 3 stacks) and 50% extra Movement Speed that decays over 2s.
Luo Yi counters heroes with low mobility such as Eudora and Gord because they are easy targets for her Sigils and Yin-Yang Reactions.
Luo Yi is countered by Fighters or Tanks with high HP recovery like Uranus and Fredrinn because she can't deal enough damage to finish them off quickly.
