Fist weapons are visually about as exciting as non-shield offhands. I want an axe, mace or dagger. Staff seems silly for a shaman even though we can wear them. Because shields are more stylish.
I was thinking that after we land on the broken shore a member of the Shaman order would contact you letting you know that there is something amiss in the surrounding seas. You go to investigate and finding a nautilus looking creature surrounded by naga. The nautilus tells you he was Neptulon second in command and is trying to fight against the naga but the naga are slowly corrupting him. You are required to heal him back to health and afterwards he decides to follow you acting as a a shield and conjuring a Axe of water for your main hand.
