Blackfrost Guecubu

Tremorsense (Imprecise) 60 feet — Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.

Void Healing — A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Blackfrost (cold, curse, disease, occult) — This affliction can't be reduced below stage 1, nor the damage from it healed, until successfully treated with Cleanse Affliction or a similar effect; the affliction can then be removed as a normal disease. A creature that dies from cold damage while cursed with blackfrost rises as a blackfrost dead after 24 hours. Blackfrost has a counteract rank of 10.

Saving Throw DC 27 Fortitude

Stage 1 4d6 cold (1 minute)

Stage 2 weakness to cold 5 and Drained 1 (1 day)

Stage 3 weakness to cold 10 and Drained 2 (1 day)

Break Ground (arcane, earth) — The guecubu stomps, and the ground breaks and ripples in a 30-foot emanation, erupting in razor-sharp, crisscrossing spikes of rock that deal 3d8 piercing damage to creatures in the area (DC 26 Reflex save).

The area becomes difficult terrain and hazardous terrain, with each square dealing 3 piercing damage to a creature that moves through it. A guecubu is immune to these effects.

Ground under the effects of a Consecrate ritual or a Circle of Protection spell tuned against evil or chaos can't be affected by this ability.

Shattering Death (cold) — When the blackfrost guecubu is destroyed, it shatters and fills the air around it with a cloud of razor-sharp shards of ice. Creatures in a 10-foot emanation take 8d8 cold (DC 26 Reflex). Creatures that critically fail this save also take 1d6 bleed.

Shove into Ice (arcane, earth) — When the blackfrost guecubu successfully Shoves a creature into an ice or frozen earth barrier, the target must succeed at a DC 26 Reflex save or become merged with the barrier, with the effects of One with Stone until the target Escapes.

Tundra Glide — The blackfrost guecubu can Burrow through any frozen earth, ice, or snow, not including rock. When it does so, the blackfrost guecubu moves at its full burrow Speed, leaving no tunnels or signs of its passing.

Wrathful Misfortune (arcane, curse) — A creature damaged by a guecubu must succeed at a DC 26 Will save or become cursed with consummate bad luck. The creature becomes Clumsy 2.

Each time that creature rolls initiative, on their next roll they must roll twice and use the worse result; this is a misfortune effect.
