I want to build my 5* Sakura but don't know how because i mostly play with Brave Veronica but I liked Sakura since the beginning so I decided to build her, she's +Res (-Spd but I can give her one merge) But don't know with that ivs which build should I give her. If recomended I'll invest in her
The thing about Healers is unless you go with the boring (but effective) Pain+ Savage Blow build there best off filling in boosts where the team they are on needs them.
For a fairly budget build for a +Res Sakura, maybe Mirror Stance for her A (from a 4* Gharnef), Even Def Wave Seal (or a Drive/Tactics) and a Drive in her C slot (or Tactics if on a mixed team). This allows her to buff her Allies and on Even turns she'd have 30 Defense which would likely help her survive if the enemy got to her.
Live to Serve or Wings of Mercy would make decent B skills. Weapon, Assist, and Special are completely up to choice, Though if using Even Defense wave I'd avoid the Earth Balm skills.
