The Great Flood

The Great Flood is a many-headed plague-serpent whose every breath spreads contagion and whose heads strike on their own initiative, a deluge of fang and disease that overwhelms a party before they can find its rhythm.

Bitter Breath (aura, disease, poison) 90 feet. If a creature ends its turn in the aura, it's exposed to the Great Flood's flood breath disease.

Coordinated Actions The Great Flood's multiple heads allow them to act on two separate initiatives, rolling initiative twice and acting on both results. They can't Delay. At the start of each of their turns, they gain 2 actions (see Multiple Reactions below for reactions).
