@XLIW95 Well let's say you want a extremely high sneak ability, first you will have to train in the first lowest sneak, then level it up to the next one, then level up that one and so on till you hit the one you want. Technically speaking it doesn't let you easily be overpower but it does let you grind to be overpower, and yes if you want you can be weak as the old abilities you grind will still be there.
