If Shemeshka fails a saving throw, she can choose to succeed instead.
Shemeshka has advantage on saving throws against spells and other magical effects.
Shemeshka carries a magic crown called the Razorvine Tiara. In the hands of anyone other than Shemeshka, the Razorvine Tiara functions as a tentacle rod that deals slashing damage instead of bludgeoning damage.
Shemeshka uses Arcane Flux or Spellcasting. She then makes one Claw attack or one attack with her Razorvine Tiara.
Shemeshka causes a surge of arcane energy to burst around one creature she can see within 120 feet of herself. The target must make a DC 18 Dexterity saving throw. On a failed save, the target takes 45 (7d12) force damage and has the incapacitated condition until the end of its next turn. On a successful save, the target takes half as much damage only.
Melee Attack Roll: +10 to hit, reach 5 ft., one target. Hit: 10 (2d4 + 5) slashing damage plus 14 (4d6) poison damage.
Melee Attack Roll: +10 to hit, reach 15 ft., one target. Hit: 10 (3d6) slashing damage plus 9 (2d8) necrotic damage. If the target is a creature, it must succeed on a DC 15 Constitution saving throw, or its speed is halved and it has disadvantage on attack rolls and saving throws until the end of its next turn.
Shemeshka utters a magical word to interrupt a creature she can see that is casting a spell. If the spell is 5th level or lower, it fails and has no effect. If the spell is 6th level or higher, Shemeshka makes an Intelligence check (DC 10 + the spell's level). On a success, the spell fails and has no effect. Whatever the spell's level, the caster gains the poisoned condition until the end of its next turn.
Shemeshka casts one of the following spells, requiring no material components and using Intelligence as the spellcasting ability (spell save DC 18):
At will: alter self, darkness, invisibility (self only), mage hand, prestidigitation
2 each/day: detect thoughts, dimension door, suggestion
1 each/day: banishment, contact other plane (as an action), mind blank
