Dimensional Crash (T3, W3)

Level12

You instantly transfer yourself from your current location to a spot within range that’s occupied by another creature, otherwise functioning as per dimension door. You take @[1d6 bludgeoning damage][roll 1d6 as damage for 'Dimensional Crash'], and the other creature takes @[3d6 bludgeoning damage][roll 3d6 as damage for 'Dimensional Crash'] (Reflex half). Attempt a @[bull rush combat maneuver][roll 1d20 + 2 + character.caster.level + character.keyAbility.modifier as attack for 'Dimensional Crash'] against the other creature, using your caster level + your key ability score modifier + 2 as your attack bonus. Compare the result to the target’s KAC + 8, as normal. For every 5 feet the creature travels this way, it takes an additional 1d6 bludgeoning damage. If your bull rush combat maneuver fails, you immediately move to the nearest available space; this movement doesn’t provoke an attack of opportunity.
