how can i squeeze 14 million more damage out of this so i can insane at 68? my sena is ue40 with maxed ex-skill so the healing part is fine kinda.

they're low hp so everything chunks them and i have to make awkward rotations to continually heal keep the heal up. i got a max ex seia but i also got stuck at 14 million hp with her when i swapped her with d.aru

should i try swapping kikyou with seia so i can spam hananko more often instead of caring about the defense down
