Haha nice lore there. Apparently he gifted someone some of his teeth hence then made into that beautiful axe and some jealous/greedy fools tried to kill him for it...sadly they apparently ended up toasty!
I like that....we need more uniques in the game like this!
Even better....I'd love having certain uniques, which are lore-tied to monsters, to spawn the actual monster in the world if the item has been found. Wouldn't it be awesome to have a chance at Sarog's maw yourself if his axe exists in your current game? The possibilities sound fun!
