MY FATHER'S LEGACY: Once per turn when an opposing character is placed, after resolutions you may place that character up to 2 squares away from their current square.

i can't figure out, is this a Once per turn/free action?

It is once per turn, it is not an action of any type however.

An example of how it works would be if an opposing character is placed by Telekinesis on the opponent’s turn, after resolutions you could choose to place them up to 2 squares away from where they were placed.

ok. thanks Man!
