NY Hrid, Plus speed minus Hp

Well there are many different routes you can take. You could use his common tank builds or invest in his speed. Speed focused would like fury or life and death (still relatively good bulk) in the A slot. Tank builds prefer bond skills, distant counter, steady stance 4, fort/def res 3,etc.

Defensive support or tank builds would prefer the safeguard, barrier blade, default weapon. Slaying, wo dao could work for a more hybrid set with the appropriate defensive refine of one's voice would be better off keeping his default sword with a speed refine for offensive support or classic slaying edge/wo dao. The hp boost along with refine will cancel the bane and further add to his bulk. More consistent, reliable damage compared to his default sword or firesweep. His sister and legendary ryoma use firesweep better.

B slot can be renewal, chill speed, his default quick riposte or desperation with enough speed buffs. C skill is adaptive to one's team. I like a stat booster, distant/ close defense, bond skill, quick riposte if not used in the b slot and niche iote's shield.
