Having a piece that can move to any empty spot and can't be countered by any other piece is simply unfathomable
even though it can't not help capture by being adjacent to another ally piece, it can help in many other ways by creating barriers for enemy pieces and getting too close to the enemy leader, threatening to smother them
when combined to the Tactician, the Wisp is simply too annoying and menacing
Its ability should not be a passive, but active, at least then it could be countered by Jailer.
