It seems this power is giving me lots of problems
My rogue player asked me the other day to use it from far away to start an ambush. Since there were no enemies 'nearby' I allowed him to 'start' a shadow walk maneuver. In his next turn he appeared 'nearby', that is, not engaged, and I told him to makr the roll then as a free action. He did it and moved, engaged and attacked enemy for double damage. Do you think this is a correct handling of it? My main concern is about the roll: I let him to make a free roll since the previous round he didn't do anything at all.
