5th-Circle Primordial (Conjuration)
Casting Time: 1 action
Range: 300 feet
Components: V, S, M (a few grains of sugar, some kernels of grain, and a smear of fat)
Duration: Concentration, up to 10 minutes
Swarming, biting locusts fill a 20-foot-radius sphere centered on a point you choose within range. The sphere spreads around corners. The sphere remains for the duration, and its area is lightly obscured. The sphere’s area is difficult terrain.
When the area appears, each creature in it must make a CON save. A creature takes 4d10 piercing damage on a failed save, or half as much damage on a successful one. A creature must also make this save when it enters the spell’s area for the first time on a turn or ends its turn there.
At Higher Circles. When you cast this spell using a spell slot of 6th circle or higher, the damage increases by 1d10 for each slot above 5th.
