I mean, losing out on power buffs and combat skills in a world of swords and magic certainly sucks, but appraisal (when it's a rare skill) and the ability to summon medicine at minimal cost would go a decent ways on making up for that (depending on if the medicine he summons can change type at will then it might turn super OP too, like if he can summon ultra tier healing potions or permanent stat boosting medicines too)
