Description
I hate the gods. They took my love, my life, everything I am. I will punish them by taking from them what they most love: life. All your little lives that are so precious to them.
Caira Xasten is a cruel ur-priest, a foul thief of divine energy who bends it to her will. Driven by an insane desire for revenge and emptied of compassion and mercy by the tragedies of her life, she seeks to lift the burden of her grief.
Goals
Caira Xasten wants to destroy the world. She doesn't want power—she wants revenge. Years ago, her lover and colleague was struck down by a falling meteorite. The chances of such an accident were so slim that she blamed the gods. Robbed of a life with the one person she loved more than anything, she went insane and bent all her considerable resources to visiting ruin on those entities she despised. She cares nothing for her own life or for the deaths of those who stand in her way.
Using Caira Xasten
Caira Xasten is a powerful adversary and one with unreasonable goals. For much of the campaign, she can be a faceless villain, a distant threat protected by layers of minions. The encounters the party has with her as the campaign unfolds should be through minions, such as when the minions steal the forbidden tome beneath the cathedral, attempt to harvest angel tears, or scour the land for the book of vile darkness. When she begins to cast apocalypse from the sky, the party should finally uncover her identity and confront her in the depths of her hidden lair.
Description
Time has not been kind to Caira. Whip-thin, tall, and fierce, she has a face that reveals the madness and corruption that has haunted her since she vowed service to Atropus. Her once-lustrous long, black hair now hangs loose and wild where it's not caught in tangles. Deep crow's feet stretch out from the sides of her red-rimmed eyes, and her mouth is frozen in a grimace. Caira wears tight-fitting gray breeches and a pale yellow shirt, both of which are pierced with small holes and covered with old stains from her experiments.
Traits
Anti-Heal
Caira can activate or deactivate this feature as a bonus action. While active, creatures within 45 feet of Caira can't magically regain hit points. A creature that were to magically regain hit points must instead make a DC 19 Constitution saving throw. On a failed save, the creature takes necrotic damage equal to the hit points it would have regained.
Dark Knowledge
After Caira makes an attack roll, ability check, or saving throw, but before the outcome is determined, an additional d20 can be rolled. Caira chooses which of the d20s rolled is used to determine the outcome. When she does so, she takes 12 (5d4) necrotic damage, which can't be reduced or prevented in any way.
Evasion
If Caira is subjected to an effect that allows her to make a Dexterity saving throw to take only half damage, she instead takes no damage if she succeeds on the saving throw, and only half damage if she fails.
Godhate
Caira has advantage on saving throws against divine spells, which are spells cast by clerics, paladins, druids, rangers, celestials, and other sources the DM deems appropriate.
Legendary Resistance (3/Day)
If Caira fails a saving throw, she can choose to succeed instead.
Sneak Attack (1/Turn)
Caira deals an extra 14 (4d6) damage when she hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of Caira that isn't incapacitated and Caira doesn't have disadvantage on the attack roll.
Spellcasting
Spellcasting
Caira is a 17th-level spellcaster. Her spellcasting ability is Wisdom (spell save DC 19, +11 to hit with spell attacks). She can cast hold person at its lowest level at will, without expending a spell slot, and she adds her Wisdom modifier to the damage she deals with any cantrip. Caira has the following cleric spells prepared:
chill touch, minor illusion, toll the dead, vicious mockery
cure wounds, inflict wounds, mage armor, magic missile
blight, Evard's black tentacles, greater invisibility
danse macabre, insect plague, negative energy flood
circle of death, create undead, eyebite
crown of stars, finger of death
Abi-Dalzim's horrid wilting, feeblemind
Actions
Multiattack
Caira makes two attacks with her frost rapier.
Frost Rapier
Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 5) piercing damage plus 7 (2d6) cold damage.
Gaze of Corruption (Recharge 6)
Caira targets one creature she can see within 30 feet of her. The target must succeed on a DC 19 Constitution saving throw or take 16 (3d10) necrotic damage and be poisoned for 1 minute. The poisoned target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Dark Speech
Caira takes 13 (2d12) psychic damage, and each creature within 60 feet of Caira that can hear her must succeed on a DC 17 Wisdom saving throw or be charmed or frightened (Caira's choice) for 1 minute. A charmed or frightened target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Reactions
Steal Magic
In response to being targeted by a spell or being included in a spell's area of effect, Caira can prepare the spell for herself, treating it as a cleric spell until she completes a long rest. Caira can only prepared one spell in this fashion at a time. If she uses this feature again on a different spell, the old spell is immediately unprepared.
