# 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).
