Evard's black tentacles

Evard's black tentacles, or simply black tentacles, was a conjuration spell that conjured tentacles to grapple and restrain opponents. It was presumably developed by Evard.

Effect
This spell conjured many rubbery black tentacles that erupted from flat surfaces and grabbed, grappled, and crushed everything in a  diameter circular area for a brief time according to the level of the caster. In a later version, the tentacles would try to restrain anything that entered or stayed in a square area, and caused bludgeoning damage, for up to a minute.

The area that was covered by the tentacles would be difficult for creatures to traverse.

Components
Verbal and somatic components were required to cast this spell, as well as a piece of a tentacle from a giant octopus or squid.

History
Evard's black tentacles was apparently unknown to the Netherese; it was not recorded as being known to them. By the, it was known only to southerner spellcasters.

In the mid–14 century DR, Evard's black tentacles was still a rare spell in the Realms. By the, the Halruaan mage Daltim Flamefist had developed a variant, Daltim's fiery tentacles, simply adding blue-white flame to the black tentacles. Kyristan instead formed the tentacles of life-draining negative energy, developing Kyristan's malevolent tentacles.
