Calcifda

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.

Calcifda is Sickened 1 in bright light.

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.

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.

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).

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).

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