Just leveled my to 25 (yay!). However, the whole quest is about learning Quick Draw... something we get from Ol' Fish Eye for free when we turn level 25. The dialogue mentions being quick and even has "quick draw". Every enemy in the Rawhide Bill boss fight has Quick Draw like other quests in which you learn a talent. This quest gives Rain of Mortarshells. I think maybe it should be switched to the quest makes sense.
