Jellyfish Swarm
Source product: Cyclopedia of Common Animals
Pages: 99
Section: Jellyfish
Swarms of jellyfish can cause swimmers to become partially or wholly paralyzed, potentially leading to death by drowning. These are normal jellyfish which prey on smaller fish, so any damage they cause adventurers is purely incidental. Jellyfish are essentially mindless, and therefore immune to mind -affecting spells and effects.
