Gelatinous Cube
| Harper Field Dossier | |
|---|---|
| Combat reference | |
| Type | Ooze — a ten-foot cube of near-transparent slime that scours the deep tunnels clean |
| Vulnerabilities | None special; it is simply not very hardy |
| Resistances | None known |
| Immunities | Sees nothing and cannot be blinded; unmoved by fear or charm (a mindless ooze) |
| Condition Immunities | Blinded, charmed, deafened, exhaustion, frightened, prone (lore of oozes) |
| Strong Saves | None — slow and witless |
| Senses | Blindsight; it feels the warmth and tremor of living things, not sees them |
| Movement | Creeps slowly along passages, filling them wall to wall |
| Notable Abilities | Engulfs a creature that touches it or that it shuffles into, holding and slowly dissolving it; so clear it is all but invisible until it moves — the unwary walk straight in |
| Provenance | |
| Knowledge | One encounter, in the dwarven barracks of Garmok's Mine |
| First Encountered | Session 44 |
| Filed by | The company's own account |
The Harpers' Read
Barely a monster — a hungry transparent box that drifts the tunnels eating whatever it bumps. The danger is entirely that you do not see it: it is near-invisible at rest, drawn to warm sleeping bodies, and anyone who blunders into it is engulfed before they know it is there. Keep a watch that is actually watching, strike it from range, and it falls quickly. It is tough only in that it is dim and persistent, not in any real resilience.
Encounters of Record
Session 44 — The dwarven barracks
After clearing the mine of devils, a dragon, and cultists, the company bedded down to rest. Alexios stood watch but nodded off, and a cube oozed in toward the warm bodies and tried to engulf him. He twisted clear and roused the others, who finished it without much trouble before finally taking their long rest.
