As an action, you teleport yourself to an unoccupied space you can see within 20 meters. A thunderous boom sounds, and each creature other than you in a sphere centered on the space you teleported from or the space you teleport to must make a Fortitude saving throw, taking 1d10 concussion damage on a failed save, or half as much damage on a successful one. The thunder can be heard from up to 100 meters away.
You can bring along objects as long as their weight doesn’t exceed what you can carry.
You can increase the damage by 1d10 for each additional mana or psi expended.
