I find that rather useless even in combat builts to be honest. The only time Lona will get grab as a combat build is when she is red in the stamina, crawling(haven't seen any enemies tries to grab when not crawling cause of low weak and sexy). And you can't sex atk when you have no stamina. And if I have stam, I am fighting. And for nympho build, it's one HP damage. They would die from orgasm before HP depletion.blood lust make her cause RED damage, which depends on combat skill, so if you go physical builds you can also kill the males who rape Lona in sex fight, by red damages.
Any reason why you forgo arm, butt and vagina piercing? Without those, I am so much less consistent with making the enemies horny. By being naked with all those piercing(minus face and nose), I can confidently say 95+% of the orkinds, fishkind and human enemies goes full batshit masturbation mode when seeing me. And since I juice them instead of waiting for them to rape me, I don't take any HP dmg.Get belly and back piercings and go mid-less. You still get the benefit of other armor pieces while having Weak above 50.
