Maz throws all images of running away out of the window! He was a fighter for crying out loud! Well, a mage, but he was raised and trained by the dark side of the city! And he already backed down once today, he won't do so again!
Deciding it's time to reveal himself, he figures it'd be best if he can disable them all.
With this in mind, he starts his attack. First he'll make it hard for them to move. He lifts his hands, and the whole area around them seeming to shake and move around, or at least to the hobogoblins. Unfortunately, it affects some of the ghost warriors too, but not all of them.
