QUEST TEXT AND DESCRIPTION
“Hello there, adventurer! Uh… I know my bulging sack is quite the eyegrabber, but my face is down here! I am the mighty Promotheus, Giver of Class Promotions! I was initially going to fill in for Atlas, but after I saw what Kratos did to him, I decided to lay low in a more obscure game for a while! Good thing for that too, because it looks like you could use a promotion what with you being a Beginner and all that! Come talk to me once you’re level 10.”
HOW TO COMPLETE QUEST
It doesn’t get any simpler. Once you reach level 10, come talk to Promotheus to complete the quest.
