The Fight
Every round
Drowning Curse
She rescans for the enemy carrying the most spellcaster levels and deepens a stacking acid curse on them alone, growing with every stack.
The instant the stack reaches 6
Dragged Under
A Fortitude save or the target is paralyzed - the stack resets on them, but unlike Serathiel's Ledger this payoff is pure control on the victim, never an outward damage nova.
Once, at 50% hp or lower
The Deep Answers
A single spirit ally rises from the flooded dark to fight at her side for the rest of the encounter.
Why These Numbers
Flooded Cavern (singular - distinct from the already-covered plural Flooded Caverns) tops out at CR12 with Mother Ilse Cade, the Drowned Theurge; Kessa is pitched above at CR15. She's the bestiary's first Shaman - a real dedicated `Shaman` spells.2da column, a genuine full 9-level nature/spirit progression, reaching roughly 6th-level spells at 12 levels here. No epic spell: short by level count, not by class design.
