I gave Alexander Gifted Item: Disguise Artifact for his extra Benefit. One quick question though; I couldn't find the answer to this in the Core so I'll assume it's up the the GM, but do you have to be within a certain distance from Disguise Artifact for it's disguise to stay up, or will going too far away make it wear off early?

You've gotta have the Artifact on you in order to use it. Same will go for all Artifacts.
