Hi guys, i have a question about the card Channeling. The card text says "You may spend 1 movement point during your turn to move 1 image token 1 space." My doubt is, can i spend 1 fatigue to gain 1 movement point, and use it to trigger the ability, since the card doesn't say it must be a movement point gained by a Move action? And can i do it multiple times during a turn?

Yes and yes. There is no limit imposed ("once during your turn...") nor is channeling exhausted, so the text can be used as often as you trigger it. Notably, this is really the only way images move since they aren't familiars and don't activate.

If you buy the illusory path skill, you can move the image one space when you gain the movement point with fatigue, and move it another when you spend that point. You images can be super mobile... but then you aren't moving much, and drain fatigue pretty quickly.
