Summon insects

Summon insects is a monster spell favored by aligned priests. When cast, many insects are created. If a are extinct or genocided, snakes, S, will be created instead. If snakes cannot be created either, nothing will be created.

Aligned priests are often located in the Sanctum and on the Astral Plane. At that point insects pose no danger to the player so it is actually helpful having the priests cast this spell as the insects act as a buffer between the player and the tougher monsters.
