Question

the best armour set best sword or staff whatever more power-full please need help

Answer 1

Umbra,who lives in the Fort of Vin Dasel. Which is on the shores of Lake Rumaro,has the most powerful sword in the game its called the Umbra,she also has a snazzy set of ebony Armour too. Retrieving the sword is also a quest for the Daedric god Clavicous Vile,but don't give him the sword,all he gives you in return is a S****y mask.

Hope I helped!
