Alien Limb (3.5e Spell)

The enemy feels a terrible pain in their body and they watch in horror as an eldritch tentacle (often resembling a length of animated intestine) bursts from their skin like a worm, and immediately begins to attack them. Each round on your turn the tentacle attacks its host, using the host's BAB and strength to determine its attack and number of attacks and any special abilities of the host (if it applies to all their natural attacks), dealing 2d10 + strength modifier in bludgeoning or slashing damage. The victim has no control over the aberrant growth.

The tentacle can be attacked and destroyed. It has an AC of 10 + your caster level, and 2 hp per HD of the opponent. However, dealing damage to the tentacle deals damage to its host as well, and so cutting it off is as much of a pain sometimes as letting it continue hitting you.

Material Component: A squid tentacle.
