This spell causes a tentacle of magical flame to snake forth from any existing source of natural or magical fire. The flaming tendril is 10 feet long, has AC 7, can be hit only by magical weapons of +2 or better, and has hit points equal to double the caster's level.
Any creature within 20 feet of the tentacle is subject to attack as directed by the caster. The victim must attempt a saving throw; if successful, the subject has avoided entanglement, but suffers 1d6 points of fire damage from contact with the tendril. If the saving throw is failed, the victim is entangled by the flaming serpent and suffers 3d6 points of fire damage each round until the tendril is destroyed or the spell expires.
If the fire source from which the tentacle emanates is extinguished, the remaining time that the fiery constrictor may exist is cut in half.
The material component is a red dragon's scale.
