oh, oof... didn't see that part before lol... edit: now that I think about it, it probably does keep the 99+
hime keep the 99+ (if anyones dumb enough to dump + effect on a hime aka 2017 me) you keep the + when the hime is awakened, yet her LB and level reset... i'm pretty sure it's like that for T4 weps, you keep the bonus you worked hard to get but you just have to work on the SL again, and the weapon is made FLB for you anyway so...
