Till Earth

More commonly used for breaking hard soil at planting time, this spell has found use in battle in desperate times. When you cast this spell you claw your hand and thrust it into the air, and the earth responds. A furrow in the soil extends out from your feet in a line to the spell’s range. Creatures in the spell’s area take 1d6 bludgeoning damage and are knocked prone. A successful Dexterity saving throw negates the effects for that creature. Creatures burrowing in the soil have disadvantage on the save, while those larger than your size have advantage on the save.

The spell fails if cast on an area of solid stone or brick, or if you are not on the ground, and ends short of its full range if it encounters solid stone or heavy masonry. Cobblestones and thin wood are weak enough to be sundered by this spell.

The spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
