Thank you, all. I read it creature’s first, but then thought it made more sense for it to be the Magus’. Wanted to check and see if there was a consensus/official interpretation before making a character and finding out in the middle of play.
Is it the creature’s or the magus’ reach that determines where dimensional assault can go? Is it one square where the magus can reach the creature? Or one square where the creature can reach the magus?
