Serpent Plague

5th-level conjuration

Casting Time:1 action

Range:300 feet

Components:V, S, M (3 snake tails)

Duration:Concentration, up to 10 minutes

A swarm of small crawling and flying serpents fills 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 swarm appears, each creature in it must make a Constitution saving throw. 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 saving throw when it enters the spell’s area for the first time on a turn or starts its turn there.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d10 for each slot level above 5th. Alternatively, at your option, if you cast this spell using a spell slot of 7th, 8th, or 9th level, a creature in the spell’s area of effect on a failed saving throw takes 3d10, 4d10, or 5d10 piercing damage, respectively, plus 1d10 poison damage and is poisoned until the end of its next turn; on a success, the target takes half as much damage and is not poisoned.
