@Slenn: Sorry, but it's a sword made of pure magical force. Technically it's not even supposed to be affected by physical attacks at all.
With Gwen making a retreat from the arena, Weizoth's spiritual sword cleaved into the concrete behind her. It attempted to follow after Gwen, but once it got to a certain distance it winked out of existence.
The bullet passed through the Wraith's body harmlessly. It continued after Gold and his large bird. As it got closer, Gold's Fearow would feel an unnatural aura coming off the creature that would make it want to do nothing more than flee. As it got even closer, it attempted to simply touch the Fearow, and if it were successful in doing so, would make the creature feel significantly weaker.
As his minion was attacking his targets, Weizoth followed after them all on foot, though he was significantly slower than his Wraith and was bound to the ground, so he had to run as fast as he could to keep up.
