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

Ebb

Every 3rd round, above 50% hp

The tide draws back - a root and a blind, and a ward settles over her while it does.

II

Flood

Every 2nd round, at or below 50% hp

The tide comes back in hard, cold and fast, and she strikes harder while it runs.

III

The Cycle Quickens

As she takes damage

Ebb and Flood never stop alternating - they simply come faster.

Why these numbers

CR 8 is set against Goblin Coast's own real ambient ceiling, not auto-computed from level alone - a genuine Druid 8 build at 8 total levels.

Hit points (56) 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 Mother Tideglass is ever up in Goblin Coast at a time.
