AngeLofDeatH clearly states the use of pet lethe scrolls. Lemme add a bit here. Players use Forgotten Scrolls to add/remove their stats. Supposing I'm a mage and I have added 3 STR to my char. I want to remove the 3 STR and add to INT, i use forgotten scrolls to do that, remove STR and add to INT, but its entirely up to players to use that.
Same goes for Pet Lethe Scrolls, where u add/remove stats to/from ur pet to make them stronger.
