Demonstar
(Evocation)

Range:  0
Components:  V, S, M
Duration:  1 round per level
Casting Time:  8
Area of Effect:  One target
Saving Throw:  Special

This powerful attack spell is used exclusively against natives of the lower planes. Against other creatures, it is absolutely harmless. When the spell is cast, a star appears in the hand of the wizard, and travels at very high speeds to implant itself on the creature's forehead, or the nearest equivalent of a forehead. Then the star starts to glow very brightly and with great heat. The demon gets to make his magic resistance roll, but at -30%. If he fails his saving throw, he gets a saving throw versus spell every round to reduce some of the spell's effects.
The star does 10d6 HP of damage per round, and immobilises the demon with pain. The saving throw is for half damage and the ability to act, despite the pain. The spell also blocks any gate attempts by the demon. This blocking of gate attempts stops when the spell duration is over or the demon is dead, whichever comes first.
The material component of this spell is a golden star.
