If i assault a prov and cast teleport on it, will the mages that are casting it join the big battle, have a separate battle or appear after the battle (wether the big battle was won or lost) ?
Not that I've ever tried it, but offensively I guess you might be able to teleport in for a "pre-battle" to cast, say, some Soul Slays or Horror Marks, and then a Returning to get out quickly (I assume if you Retreat from Teleport you get lost in The Void)
