Dimensional thunder

Dimensional thunder is a teleportation spell used by swordmages, most often those of the raging storm path, who prefer to use the forces of thunder and lightning together. With dimensional thunder a swordmage can cut a hole in the fabric of the Prime, slipping through into to another location, how far away depending on the swordmage's constitution. In the process, the swordmage brings with them a wake of thunderous sound, which can be deadly to nearby enemies and which booms outward from the swordmage's weapon. The sound echoes for some time afterwards, causing continuous pain to a swordmage's adversaries. It is not an easy spell to cast, however, and can only be used once per day.
