Wasp swarm

Kind Environmental or Procedural Threat

Wasps often colonize crinwin nests, living symbiotically among them so the nests thrum and buzz ominously. A single sting hurts like the dickens and takes effort not to cry out. When a swarm engulfs you, take 1d4 damage (ignores armor) and you're wracked with pain; doing anything other than curling up and writhing means Defy Danger, likely with CON. Each subsequent swarm hit increases the die one step, up to d10.
