Found a variant of this online but I feel like it would be too difficult for this expansion so here's my version:
"Fists" only leveling
-Start as any class that can dual wield fist weapons
-Any race (I prefer orc because of the racial ability but you can choose whatever you want)
-No potions
-Any armor but you can't wear a helmet or a chest piece
-You can only spend 10 talent points
-You can't group up with other people (unless they're also doing the challenge)
-No dungeons
