Description: You create two Colossal-sized masses of rock, dirt, and stone and slam them together against a single creature between them. The clashing rocks appear up to 30 feet away from the target on opposite sides and rush toward it with a mighty grinding crash. You must make a ranged spell attack to hit the target with the rocks. The clashing rocks ignore cover, and if there is a solid barrier between the target and either of the clashing rocks, the spell has a +28 bonus on the Strength check to burst through the barrier and continue unimpeded to the target. A creature struck by the clashing rocks takes 70 points of bludgeoning damage and is knocked prone. If the target fails a Dex saving throw, it is also buried under the resulting rubble as if by a cave-in.
If the clashing rocks miss the target, the target still takes 35 points of bludgeoning damage from falling rocks and is knocked prone. A successful Dex save reduces this damage to half and the target remains standing. Creatures other than the target that occupy the spaces where the clashing rocks appear or within their path (30 feet wide, 30 feet high, and up to 60 feet long) must also make Dex saves or take 35 points of bludgeoning damage and be knocked prone (save for half and remain standing). A creature can only take damage once from the clashing rocks, no matter how many times the clashing rocks pass over a target creature.
