Black Tentacles

A field of 10-foot-long rubbery tentacles will spring from the ground. The area is up to 30 by 30 feet, and they will appear from whatever surface is present, including water. The tentacles will attack any creature in the area with the intent to wrestle them (see the wrestling rules in the Basic Fantasy RPG Core Rules). They attack with the caster’s attack bonus and are considered to have a Strength of 18. There are more than enough tentacles to individually attack as many targets as can be present. If the attack succeeds, the target is held immobile and takes 1d6 points of damage each round it is held. Any creature that is not held by a tentacle may still only move through the affected area at half speed.
