In Alaska, there have been reports of these creatures raining down from the sky, landing on gardens, streets, cars and unsuspecting passersby in Alaska. They are lampreys and scientists suspect that they are being dropped by gulls after being plucked from the ocean.
Rain of Petromyzontiformes
This spell summons a number of hungry lampreys (number appearing equal's spell level) to appear approximately 5' above the target. The lamprey's are disorientated, angry and slimey, and will cling to armour, clothing and skin. They do only minimal damage, but their presence creates a great disadvantage to the victim, forcing them to take a penalty to all rolls until the creatures are dislodged. It takes one complete action to remove one lamprey.
Rain of Tentacles
This spell is almost indistinguishable from an 'entangle' spell (or similar) except the victim is wrapped in strong, constricting tentacles that also moderate damage per round. A strength check is required to break free.
