would love it if someone could teach lucina hand to hand combat or that deflecting/evading is better than purposefully letting herself get harmed.
she’s got an abnormal healing magic which immediately regenerates any injury on her person and has a tendency to use the shock of her opponent to paralyze them and use it as a method of escape.
wouldn’t it freak you out / stun you if someone let a bomb explode in their palm and watch their flesh and bones practically fly everywhere and that person just let’s it happen? yeah. she does that a lot. and her magic heals and recovers everything without hesitation.
it’ll show its rejuvenation progress so no, there’s no white light or anything sparkly to embellish it. it’s all out in the open for everyone to see. blood, marrow, bone, muscle... everything. so yeah, she’d let herself get harmed if it means having an opportunity to flee.
