Convergence

Choose a point you can see within range, two lines up to 30 foot long, and 10 feet wide extend out from it on opposite sides from each other. Two large rocks appear on both ends of the lines, these rocks quickly travel towards the centre point and crash together. All creatures in the line must make a Dexterity saving throw or take 8d6 bludgeoning damage, be pulled to a space near the centre, and are knocked prone, on a success they take half damage and are not moved or knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage is increased by 1d6 for each slot level above 5th.
