The spell says it can only hold what it's given, and the stuff you hand over follows a few paces behind you.  If it leaves your presence, it's dispelled.<br/><br/>I guess you could get away with having it move things around within a reasonably short distance of you; say, Near range ('can see the whites of their eyes', or about 30 feet), and then any further and it just drops whatever it's holding.  It's a magical construct rather than an intelligent thing (I think, unless Amelia's Unseen Servant works differently?  Up to you!), so it might be just directed by magic rather than needing to be ordered around.<br/><br/>edit: xiaomei, make sure you mark an XP for Hedenabi's not-so-pretty Discern Realities roll!  Amelia should have an XP from her missed Defy Danger roll, too.
