Imprison Mind [>>] (mental, necromancy, occult) The blackfrost prophet concentrates on a creature within 60 feet, filling the target's mind with befuddling susurrations. The creature must succeed at a DC 28 Will save or take 4d8+8 mental damage and become stupefied 1 for 1 minute (stupefied 2 on a critical failure). The creature is slowed 1 as long as it's stupefied.

Raise Blackfrost [>>] (cold, conjuration, occult) The blackfrost prophet selects a point within 60 feet, then calls upon shards of blackfrost to stab up through the crust in a 30-foot burst. Creatures in the area take 2d8 piercing damage plus 2d8 cold damage (DC 28 basic Reflex save). A creature that takes cold damage from this ability is exposed to blackfrost. Until the next time the blackfrost prophet uses Raise Blackfrost, the affected area is difficult terrain.
