I have a Ariados in Omega Ruby with 5 31 IVs(HP/Att/Def/Sp.Def/Spd) and its Sp.Def is 80 at LV. 50. So, if I send it to Sun/Moon its Sp.Def is going to become 90 (At LV. 50)or I have to breed Ariados in Alola Again so the buff amplie?
Anytime it gets used in a Gen VII game. It's an automatic adjustment.
