Evard's Black Tentacles

This spell creates many rubbery, black tentacles in the area of effect. These waving members seem to spring forth from the earth, floor, or whatever surface is underfoot—including water. Each tentacle is 10 feet long, AC 4, and requires as many points of damage to destroy as the level of the wizard who cast the spell. There are 1d4 such tentacles, plus one per experience level of the spellcaster.

Any creature within range of the writhing tentacle is subject to attack as determined by the DM. The target of a tentacle attack must roll a saving throw vs. If this succeeds, the subject suffers 1d4 points of damage from contact with the tentacle, and then the tentacle is destroyed. Failure to save indicates that the damage inflicted is 2d4 points, the ebon member is wrapped around its subject, and damage will be 3d4 points on the second and succeeding rounds. Since these tentacles have no intelligence to guide them, there is the possibility that they entwine any object - a tree, post, pillar, even the wizard himself - or continue to squeeze a dead opponent. A grasping hold established by a tentacle remains until the tentacle is by some form of attack or until it disappears at the end of the spell's duration.
