Earth Spikes

Swelling up from deep underground, a massive stone spike bursts through the earth. Chose a point on the ground within range. You do not need to be able to see the point, but you must know that it is solid ground. If you target a point that is not on the ground, the spell fails and the spell slot is still consumed. A 5 foot diameter stone spike bursts out of the ground at that point. Each creature on that point must make a dexterity saving throw. Each target that fails takes 3d8 piercing damage, or half of that on a successful saving throw.

At Higher levels When you cast this spell using a spell slot of 3rd level or higher, it does an additional 1d8 damage per spell level above 2nd
