Consecrate

This spell blesses an area of a 20ft cube with positive energy. Turn undead within this area gains a +3 bonus to the affected undead challenge rating. Every undead creature entering a consecrated area suffers minor disruption, giving it a -2 penalty on attack rolls damage rolls, and saves. Undead cannot be created within or summoned into a consecrated area.

If the consecrated area contains an altar, shrine, or other permanent fixture dedicated to your deity, pantheon, or aligned higher power, the modifiers given above are doubled (+6 on the affected undead challenge rating and, -4 penalties for undead in the area). You cannot consecrate an area with a similar fixture of a deity other than your own patron.

If the area does contain an altar, shrine, or other permanent fixture of a deity, pantheon, or higher power other than your patron, the consecrate spell instead curses the area, cutting off its connection with the associated deity or power. This secondary function, if used, does not also grant the bonuses and penalties relating to undead, as given above.

Consecrate counters and dispels desecrate.

If consecrate is cast for the full two hour duration the all the spells effects are permanent until dispelled.
