Gemsight

As long as Calcifda holds a gemstone, she can see through the gem with darkvision and the effects of Truesight. When she uses her Aeon Stone (Pearlescent Pyramid) for this ability, she also knows the wounded and dying value of every creature she sees. Calcifda is blind when she isn't holding a gem in her hand.

Light Sickness

Calcifda is Sickened 1 in bright light.


Speed 25 feet, burrow 25 feet
Melee Claw +22 (agile, unarmed), Damage 3d6+11 slashing plus Coal Curse
Occult Innate Spells DC 29, attack +19; 5th Wall of Stone; 4th Clairvoyance, Read Omens, Shape Stone; 3rd Clairaudience, Earthbind; 2nd Augury, Undetectable Alignment; Cantrips (5th) Know Direction, Read Aura
Coal Curse (curse, primal)

Wounds dealt by Calcifda's claws stiffen flesh and turn the blood that runs from them into tar. Each time a creature is damaged by Calcifda's claw Strike, it must succeed at a DC 29 Fortitude save or become permanently Slowed 1 (slowed 2 on a critical failure) as its flesh stiffens like stone. If a creature is reduced to 0 Hit Points from Calcifda's claw Strike and fails the saving throw against coal curse, it's petrified and turned to coal. A creature that spends 8 hours in direct sunlight can attempt a new saving throw to remove the effects of coal curse, even if it has been petrified.

Earth Glide

Calcifda can Burrow through any earthen matter, including rock. When she does so, she moves at her full burrow Speed, leaving no tunnels or signs of her passing.

Gem Gaze (emotion, fear, mental, primal)

Calcifda holds aloft a gem and gazes into the mind of a creature within 30 feet, infusing the creature's thoughts with visions of their body slowly turning to coal. The creature must succeed at a DC 29 Will save or become Frightened 1 (frightened 2 on a critical failure).

Lashing Stone (concentrate)
Frequency once per round

Effect Calcifda makes a claw Strike that originates from any stony or tarry surface within 60 feet. A creature that fails its Fortitude save against coal curse from this Strike increases its slowed value by 1 (Slowed 2 on a failed save, slowed 3 on a critical failure).
Steady Spellcasting

If a reaction would disrupt Calcifda's spellcasting action, she attempts a DC 15 flat check. On a success, the action isn't disrupted.
