Effect: Over the course of ten minutes, this spell forms a barrier in Area: 30m Radius that is surrounded by holy water or holy branches (or their ashes). This barrier protects Target: All within that area for Duration: 12 Hours.

Any hostile against those inside the barrier must make a spell resistance check. Failure on one means they cannot cross the barrier until it is dispelled. Hostile entities take a −2 penalty on this spell resistance check, while undead enemies take a −4 penalty instead.

If a hostile entity gets inside the barrier, the targets within are immediately aware of the intrusion, and they have a general impression of where the intruder is. If one or more targets are in a natural state of sleep, they immediately wake up. However, if they are asleep due to some sort of special effect, like one from a spell, or are unconscious, they do not wake up. The targets will also wake up if the barrier is somehow destroyed, or if efforts to destroy it are made.

In order to create the barrier, the caster must pass a spell use check, then pass one spell maintenance check on top of it.
