Level 1, Ongoing, Illusion
Choose an ally: nobody can see them. They’re invisible! The spell
persists until you make a move or dismiss the effect.
So, it says choose an ally. Is that supposed to include or exclude the castor? If the castor is included, perhaps this could be written as choose yourself or an ally.
Further, does it last until *you* make a move, or until the target does?
It says the former, but the latter makes more sense to me.
