Chilling Touch
The necromancer can cause his or her hands to glow with a blue, flickering aura. This frigid radiance can both drain and paralyze the wizard's victims. First, any living creature touched by the icy hands suffers the effect of a modified chill touch spell. If the victim fails his or her saving throw, the touch causes 2d4 points of damage and (temporarily) drains 1 point of both Strength and Constitution. If the saving throw is successful, though, the victim only loses ld4 points of damage and just 1 point of Strength. Second, if the necromancer is at least 16th level, the victim must make a second save or be paralyzed for 3-12 rounds.
The necromancer can activate or deactivate this power at will. It never interferes with spellcasting. Also, the cold blue aura provides light like a dim torch (certainly enough light to walk or read by).
