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

Wither Touch

Every 3rd round, above 66% hp

A mark she plants by hand.

II

Foul Contagion

66%-33% hp

From here the mark spreads on its own - any marked creature standing near an unmarked one passes the stack across without her lifting a finger.

III

Bog's Embrace

Once, below 33% hp

Everyone in reach is rooted, and every stack anywhere on the field detonates at once.

Why these numbers

CR 22 is set against Felmist Marsh's own real ambient ceiling, not auto-computed from level alone - a genuine Outsider 4 / Druid 10 / Blighter 8 build at 22 total levels.

Hit points (255) 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 Ss'vetha is ever up in Felmist Marsh at a time.
