Guecubu
CREATURE 8Sometimes an individual performs acts of horror so unspeakable that the earth they walk on becomes imprinted by their evil. With such villains, even slaying them and scattering their bones can't rid the world of their vile presence. Their souls rise again as guecubus, gruesome skeletons made of scorched bones, rotting flesh, and befouled earth. Guecubus roams the land seeking those they deem responsible for their death.
A guecubu remembers what was done to them, and the memories of their supposed mistreatment fuel their quest for revenge. Guecubus are well-equipped to exact such vengeance. Along with monstrous power and the ability to move through earth, they retain all the cunning they had in life. These creatures are known to kill their enemies one by one, leaving no trace of their presence behind save pebbles and dust.
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.
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.
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 basic 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.
The guecubu can Burrow through any earthen matter, including rock. When it does so, the guecubu moves at its full burrow Speed, leaving no tunnels or signs of its passing.
When the guecubu successfully Shoves a creature into a stone 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.
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.
