Conjure Gnats

You summon flying insects that appear in unoccupied spaces that you can see within range. Choose one of the following options for what appears:

• 1 Swarm of Insects.
• 10 Friendly Gnats, carrying capacity of 5 grams, movement speed 40 feet.

A summoned creature disappears when it drops to 0 hit points or when the spell ends.

The summoned creatures are friendly to you and your companions. Roll initiative for the summoned creatures as a group, which have their own turns. They obey any verbal commands that you issue to them (no action required by you). If you don't issue any commands to them, they defend themselves from hostile creatures, but otherwise take no actions.

The GM has the creatures' statistics.

At Higher Levels. When you cast this spell using certain higher-level spell slots, you choose one of the summoning options above, and more creatures appear: twice as many with a 4th-level slot and three times as many with an 8th-level slot.

After 4th Level, the Gnats get an attack.

Swarming, biting gnats 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 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 ends its turn there.

When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4th.
