Oculo Swarm

Oculo Swarm is a large aberration (Challenge Rating 4).

**AC:** 15 **HP:** 110 **Speed:** [object Object] **STR:** 10 **DEX:** 20 **CON:** 16 **INT:** 8 **WIS:** 15 **CHA:** 17 _This collection of hundreds of eyes floats along, trailing ganglia and dripping caustic fluid that sizzles when it hits the ground._ **Failed Experiment.** An oculo swarm results from an experiment to create a live scrying sensor that went poorly. Once set loose, these horrors attain a form of distributed self‑awareness. Exactly what motivates them is unknown, except that they are driven to survive. **Flesh Stealers.** A weakened oculo swarm can reinvigorate itself by tearing fresh eyes from almost any type of living creature. If a badly depleted oculus swarm escapes from battle— and they seldom fight to the death unless cornered—it attacks lone creatures or weak groups until the mass of gore-spattered eyeballs is replenished. The more dismembered eyeballs the swarm contains, the more powerful its paralyzing resonance field becomes. **Single Eye Scouts.** The entire swarm sees what any single member sees. Before attacking or even entering a potentially dangerous area, individual eyes scout ahead for prospective victims or dangerous foes. A lone eye has no offensive capability and only 1 hp. It can travel only 100 feet away from the main swarm, and it must return to the swarm within an hour or it dies.
