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

Opening Cast

Above 66% hp

Leans on the reliable half of a real Wizard 4 / Cleric 4 / Mystic_Thurge 4 spellbook to test the room before committing anything further.

II

Escalation

66%-33% hp

Draws on the sharper end of the list - Cure Moderate Wounds, Contagion, Ruin - as the fight tightens.

III

Last Working

Once, below 33% hp

Spends what's left of the prepared list in one committed working rather than holding anything back.

Why these numbers

CR 12 is set against Flooded Cavern's own real ambient ceiling, not auto-computed from level alone - a genuine Wizard 4 / Cleric 4 / Mystic_Thurge 4 build at 12 total levels.

Hit points (108) 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 Myrvol Tide-Scriptor is ever up in Flooded Cavern at a time.
