Wall of Evil

The wall of evil spell creates an invisible, immobile wall of sheer diabolical evil. This barrier is a vertical curtain-up to one 10-foot square per level of the caster. Paladins and other good-aligned creatures that pass through the wall feel distinctly unwelcome. A natural animal, unless unusually loyal, will shy at the barrier and will not cross if a saving throw vs. spell is failed.

Undead creatures cannot be turned by a priest separated from them by this barrier. Further, any spell cast by a good-aligned creature passing through this barrier is weakened-target creatures and objects receive a +2 bonus to their saving throws.

If subjected to a detect evil spell or ability, the wall of evil bursts into sight, resembling a translucent wall of blue flame.

The wall of evil lasts for as long as the wizard concentrates on maintaining it (movement up to half normal is allowed), and for one to four rounds after concentration has ended.
