oh hey, GrimWulf is back.
Yeah, you are free to roll the resistance tests for Spirits. It makes things go faster. At Force 8 it gets two Optional Powers, so which ones are you giving it?
But just to confirm, Air spirits are your Illusion spirits. You can still ask it to attack, but it will prefer to use things like Confusion, Concealment, Fear and the like. If you want something that is going to tear this helicopter a new one, you would want to use a Beast spirit.
And you have 2 edge total, so you're down to 1 now.
