Overview
Yuanwu is a 4★ Electro Gauntlets Support from Huanglong. Version 3.6 still lists him as the honest Jinhsi substitute. Field time is one Resonance Skill and an outro. He is a specialist, not a general Electro carry.
Rotation
Healer outros. Yuanwu intros, Resonance Skill to plant the field, outro immediately. Jinhsi or the Electro carry intros into coordinated pings. Do not punch for twenty seconds.
Strengths
F2P Spectro nuke teams exist because of him. Hollow Mirage is enough. Bench him only when Yinlin and Zhezhi are both free — and keep him leveled for the week they are not.
Weaknesses
Not a carry. Wrong tool if the team wants a generic battery like Lumi. Easy to over-field.
Investment
Skill first. Waveplates on a functional ER set. Abyss Surges is luxury.
Common Mistakes
Full Void Thunder CRIT as if he were Xiangli Yao. Holding the field. Vendoring him after one Yinlin pull.
