What triggers Murne's solidarity portion that gains movement points?
1. Using a move action to gain movement points.
2. Using surge to gain movement points.
3. Jyn's opportunist ability that allows her to move one space after attacking.
I ruled that only the move action triggers it as the wording on solidarity states that performing a move is what triggers it. We stuck to this ruling, however my players want to see other source confirming the timing.
