Il'setsya Wyrmtouched

Il'setya can anticipate the most likely location of a creature through their supernatural insight into the forces of chaotic probabilities and chance. This grants Il'setya the ability to sense creatures within the listed range. The Il'setya's entropy sense doesn't detect creatures under the effects of Veil of Privacy or that are otherwise shielded from divinations and predictions.

A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.

A monster with this ability regains the given number of Hit Points each round at the beginning of its turn.

Il'setya's vital organs shift and change shape and position constantly. Immediately after Il'setya takes acid, electricity, or sonic damage, she gains the listed amount of resistance to that damage type. This lasts for 1 hour or until the next time she takes damage of one of the other types (in which case its resistance changes to match that type), whichever comes first. Il'setya is immune to polymorph effects unless she is a willing target. If Blinded or Deafened, Il'setya automatically recovers at the end of its next turn as new sensory organs grow to replace the compromised ones. Effect: Protean Anatomy

Frequency twice per day Effect Il'setsya steps through a transient hole in space, instantly teleporting to a space within 60 feet that she can see.

Il'setsya's prehensile tail can hold and manipulate objects of Light Bulk or less, though it cannot be used to attack. She can spend an Interact action to use her tail to fetch objects stowed on her person, such as potions.

Il'setsya infuses her next spell with roiling currents of chaos. If Il'setsya Casts a Spell before her turn is over and the spell affects a creature, that creature is also subject to a Warpwave. If she doesn't Cast a Spell before the beginning of her next turn, this action is wasted.
