Property

When you use a power to teleport, you can instead teleport twice as the same action. The total distance you travel with both teleports cannot exceed the distance you could have traveled with the original teleport. You could, for example, teleport to a corner, establish a new line of sight, and teleport to a square not visible from your starting location, so long as the maximum number of squares teleported does not exceed the teleport power's allotted movement.

Power (Teleportation) ✦ Encounter (Move Action)
