Quick Reference
Running This Encounter
A Swarm of Wasps is best used as a threatening environmental hazard or minor encounter that emphasizes action economy over raw damage. Position the swarm to emerge from nests, hives, or disturbed locations when players trigger them. Use the swarm's mobility to harass spellcasters and ranged attackers, forcing the party to adapt their tactics. Consider combining with other creatures or obstacles to create a memorable encounter.
Combat Tactics
The swarm uses hit-and-run tactics, focusing fire on vulnerable targets like wizards or monks with low AC. They prioritize movement and evasion over standing ground, spreading out to avoid area-of-effect spells. If the swarm drops below 11 HP, it may flee to its nest rather than fight to the death.
Environment & Setting
Ideal in forests, gardens, ruins with vegetation, or abandoned structures where nests are plausible. Use difficult terrain like tall grass or rubble to give the swarm cover while limiting party mobility.
