Clunk, clunk, clunk...
Arty turned at the sound, and to his very great surprise found that skeletor was charging him from behind, sword raised to chest level. How in the blazes he'd gotten behind him even though he'd been able to see him a moment before when he'd cut the Mage in half was entirely beyond him, but it seems the universe was fickle today. Everybody kept disappearing and jumping about like this was some kind of mass temporal flux instead of a fight. It was annoying.
The blade was still six feet away when Arty first saw it, and he wasted no time in getting himself gone (while also keeping tabs on the fellow behind the tree, since he could actually sense him without looking). Or rather, getting his opponent gone. Anchoring himself to the ground, Arty reached out with his power and seized the air around him, throwing it toward the undead warrior at over 300 miles per hour. A gale force wind if ever there was one, and more than enough to launch the charging warrior across the field of battle, and incidentally straight toward another fellow who'd just arrived on the scene (QuietThinker).
