Combat sequence

Layered on top of the module's own combat AI, which still picks targets and positioning. The fight below moves through real hit-point-gated phases; every save DC and attack bonus computes from the stat block above at runtime.

I

Mind Lance

Above 66% hp

A lance of raw thought aimed at whoever's nearest, weakening their will along with their body.

II

Rift Scatter

Every 4th round, 66%-33% hp

Every enemy within reach is torn from where they stand and thrown to a random point on the ring around her - the party's own formation undone in an instant, the opposite of being pulled together.

III

Mummy Dust

Once, below 25% hp

Her granted Epic Spell doesn't raise the dead - it tears two Rift-Spawn Husks through the same wound in space she's been working all fight, and a wave of confusion follows them out.

Why these numbers

CR 23 is set against Desolate Tower - First Tower's own real ambient ceiling, not auto-computed from level alone - a genuine Wizard 14 / Alienist 9 build at 23 total levels.

Hit points (172) follow this project's own average-hit-dice convention, and every save/attack bonus derives from the ability scores above at runtime - nothing here is hardcoded past the phase gates themselves.

How it's wired

Boss-flagged (bypasses the drop-rate roll, two loot-generation passes) and gated to a single spawn - only one Nyveth Corr is ever up in Desolate Tower - First Tower at a time.

Recovered artifact

Corr's Rift-Splinter
