This spell prevents undead creatures from moving into its area of effect. Upon casting this spell the affected area radiates a faint blue, flickering radiance, visible to all.

Undead must successfully save vs Constitution in order to enter the warded area; those failing the saving throw cannot enter. Those who can enter the area do so without penalty. An undead creature can attempt to enter the warded area once per turn, gaining a new saving throw with each attempt.

Undead already in the area of effect must make a successful saving throw or be [Tooltip Not Found] (as the wizard spell) for the duration of the ward.

The ward against undead is stationary and has no additional effect on combat or turning. Once a particular undead creature makes a successful saving throw against the ward it does not need to make that saving throw again. Multiple wards can be cast in the same area, requiring multiple saving throws to cross or avoid their effects, though no undead will suffer more than one slow spell effect at any time. A dispel magic spell will destroy the ward, but otherwise the spell will run to the end of its duration.

Using a Higher-Level Spell Slot. The duration increases by 1 round and the area increases by 10 feet in radius for each spell slot level above 3.
