Okay. So what's that's meanEffect: You can move 3 squares, as long as you can end your
move adjacent to an enemy.
By the identity principle, a square touches all or its own sides and corners.Adjacent Squares: Two squares are adjacent if a
side or a corner of one touches a side or a corner of the
other. Two creatures or objects are adjacent if one of
them occupies a square adjacent to a square occupied
by the other.
That cannot be an exclusive or, because two distinct squares orthogonally next to each other share one side and two corners.
Ergo, a square is adjacent to itself.
Ergo, every time you move you are adjacent to yourself
Since we have previously determined that you are your own enemy in 4e rules, the power just works whenever you want it to.
And geez, that's a lot of rules lawyering to get an effect half as good as boots of eagerness or having a warlord buddy.
