I think both of these things increased Vigor, but they´re described differently.
What´s with this Atlas Armlet "raises attack power" and Hyper Wrist "raises Vigor" thingy?
This is just like some random, non-existent Relics like Holy Wall "raises defensive power" and Turtle Shell "raises Vitality" just to give an example.
What´s the matter with the earlier Relics?
What´s the difference?
