You imbue the area with positive energy.

Every undead creature entering a consecrated area takes a -1 penalty on attack rolls, damage rolls, and saving throws, and gains a further -4 penalty on all saving throws against the Turn Undead feat.

Undead creatures cannot be summoned into or created within a consecrated area. If the consecreted area contains an altar, shrine, or other permanent fixture dedicated to your deity or aligned higher power, the modifiers given above are doubled (-2 penalty on attack rolls, damage rolls, and saving throws, -8 penalty against being turned). If the area contains 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 penalties relating to undead, as given above.

Augment: If you spend 4 additional spell points, all non-evil creatures within the spell’s area gain the benefits of the good-aligned version of the Aligned Protection spell (also known as Protection from Evil).
