When cast, this spell renders immobile 1d3 undead creatures whose total Hit Dice are equal to or less than the caster's level.
No more than three undead can be affected by a single spell. To cast, the wizard aims the spell at a point within range and the three undead closest to this are considered to be in the area of effect, provided all are within the field of vision and spell range of the caster.
Undead of a mindless nature (skeletons, zombies, or ghouls) are automatically affected. Other forms of undead are allowed a saving throw to negate the effect.
If the spell is successful, it renders the undead immobile for the duration of the spell.
The material component for this spell is a pinch of sulphur and powdered garlic.
