just got cape of legerdemain but its saying unable to use item from another realm, on druid (aed)

You're able to place rams to the sides of keep doors at least on the inner which will avoid people being able to hit you

This happened for the clipped verison I selected the power one and it gave me the health one, so this time I triple checked to make sure I was selecting the power one and it gave me the defence one, I'm a wizard so neither of these are of any use.

Can this be swapped to power?
