Insect Plague must be summoned in such a way that each swarm is adjacent to. At least one other swarm (that is, the swarms must fill one contiguous area). To share the world with other creatures, you will summon wasp swarms. These swarms attack anything nearby. After being summoned, swarms remain stationary and will not pursue creatures that flee. This makes them useless at their level. You can use it as a terrorist thing to attack the PCs indirectly from the exits from open-air markets.
An area of 20 feet in radius is infested with swarming, biting locusts that are centered within the range you select. They spread around corners. During the duration of the event, the area around the Sphere is lightly obscured. Difficult terrain surrounds the sphere. Every creature in the world must make a Constitution saving throw when it appears. On a failed save, a creature takes 4d10 piercing damage, or half as much damage on a successful one. This saving throw is also required when a creature enters or ends its turn in the spell’s area for the first time.

When cast using a spell slot of 6th level or higher, the damage increases by 1d10 for every slot level above 5th. Insects were summoned to cover the realm of effect, biting and stinging everything relentlessly, . Reducing visibility to 10 feet (3 meters), and preventing spell casting. Invisibility made it impossible to avoid the swarms and the armor didn’t protect. Everything with low morale and small creatures would move at top speed in a random direction until they were far from the plague.
Insects did not chase fleeing targets but remained in the spot where they were summoned for the duration of the spell. Large fires and smoke or strong winds drove the insects away, but a fireball only cleared a small area for a while. In earlier versions of this spell, only verbal and somatic components were needed, plus a priest’s divine focus or holy symbol. Earlier versions, as well as those following the Second Sundering, also called for sugar, grain, and fat.
A swarm of insects swarms into a cloud of great quality. Creatures within the area take 1 point of damage each round, and their vision is obscured, limiting it to 3 inches. A creature with two HD or fewer flees during a line until it is 24″ from the cloud. If a creature has no more than 5 HD, it can make a morale check instead of fleeing. Swarming creatures do not move once they arrive.
As part of your action, you will expend 1 charge to summon a swarm of harmless flying insects to open up in a 30-foot radius around you for 10 minutes. The insects remain for 10 minutes, obscuring the world around you except for you. The Insect Plague moves with you, remaining focused on you until a wind of at least 10 mph disperses the swarm and ends the effect.
