The size of the Seablight nest or hyve determines the number of infectious stings inflicted each round. A tiny nest can sting 1D6 times per round, scaling up to a small hyve doing 8D6. The dice type may be adjusted based on the severity of the Psychezoa (1 pt. for minor irritation all the way up to D10 for vicious predatory swarms). Each character attacked by the Swarm is automatically stung the rolled number of times each combat round until they escape, deter, or destroy the swarm. A Swarm attacks for 2D6 combat rounds before giving up. Unless the targets are completely covered or enclosed there is no protection against a swarm. A Difficult Dodge roll can avoid a Swarm, or other means (such as an electromagnetic dampener) can be used to drive them away. Any protective gear the character may be wearing will reduce the number of stings per D6, with light gear reducing each die by –1, blightkeeper gear by –4, and complete covering meaning no stings whatsoever.
