Pretty simple really, Just add a potion that lets you “retry” your thrall’s or Pet’s Perks giving you a new random level 10/15/20 perk. (depending on the level of your thrall/pet)
I know this might be rather lazy but I thought it might be nice to not have level 20 thralls and such with useless perks and farming a potion would ideally be quicker than levelling a new thrall, Although should still require some time sink I think.
