When you've got 'str + att = 130(+) ' then you can enter the Warrior's guild. When you go the the second floor, you will see a keg on ground. When you take an inventory full with energy potions than you can start. You balance the keg on your head, after a few second you get +108 Str xp, and -10% energy. You drink the energy potion and get another XP drop. You can earn about 70K xp/h without anything required! VERY VERY VERY GOOD BOT! Please make one, this is very good method!
