Swordbirth

You drive your weapon into the ground and create a sphere of swords around you.

In a 30ft radius around the summoner, sword blades are created out of the ground. This spell deals 3d12 piercing damage to any creatures within the spell's radius, besides the caster. Creatures who take damage must then make a DC17 Dexterity saving throw against being prone. This spell is always rolled as one attack, no matter how many creatures were hit.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the damage increases by 1d12 for each slot level above 7th.
