>>2644630In case you didn't know you can remove EX lotions from a girl using special ex cleaner and the lotions return to bottle form for reuse. However you can only get one of those cleaners each month and it'll cost you 10 vip coins if you play on eng.
But that's also kind of a hassle imo and not worth doing. I would stick the single TEC on the girl of your choice and then use the generic pool hopping stm lotions for the other 2 skills if you have them.
Assuming that you currently have a girl with 3 SSR 7 STM skills that's a 21% boost to your base stm level. The generics are 5% I think? So you'd be going from 21% STM boost to 15% TEC and 10% STM.
EX skills also dont come off with regular milk items so you can stick the ex on there and then remove the ssr generic STM skills whenever you want for whatever else you want.
If you do decide to wipe the lotion skills make sure to lock your bounce/firm/shape levels so they dont get wiped too else you'll have to wait for a real lotion event to come around.
