He dissolves the threads that fuel his defensive spell to gather all of his strength...
I've dropped the spell to gain more dice on the Powerbolt spell.
And the first spirit summoned was the one with Intimidation, so it's the scary-looking one. The 'female' was the one with Movement.
Also - can i use my movement to hide behind the couch, or does it take an action? If so, then my next (free) action would be dropping prone, and then casting Invisibility from behind the cover.
Did the guard open the door? I thought that would work like this:
1. The Spirit uses Influence to make the guard open the door, as Stryker was saying something about leaving. It should've been plausible.
2. Then Stryker casts Powerbolt on his mark.
