Glowworm Swarm

Type: Bioluminescent cave-dweller

Size: Individual: 10-20 cm; swarm: thousands

Behavior: Filter-feeds on airborne spores. Harmless individually, overwhelming in swarms. Light pulses disorient predators.

Abilities:

Bioluminescence (controllable intensity)
Synchronized light pulses (hypnotic)
Numbers (crush threats by mass)

Vulnerabilities:

Smoke (disperses swarm)
Sound (disrupts coordination)
Cold (induces hibernation)

Encounter Notes: Beautiful but dangerous in large numbers. Deepkin harvest them for lighting. Swarms indicate nearby food sources (fungal blooms).
