Item #: SCP-312
Object Class: Euclid

Special Containment Procedures:
SCP-312 instances are not to be deliberately attracted or observed during outdoor operations above cloud level. Personnel assigned to high-altitude or storm-monitoring duty must wear eye-covering equipment that prevents direct line of sight with unidentified aerial masses. Should an instance be visually confirmed, affected staff are to seek immediate overhead cover (solid roof or enclosed structure) and remain under observation until gravitational and physiological effects have fully subsided. No more than four (4) instances are to be left active in any given containment region; excess specimens may be relocated only under Level 3 authorization. Direct engagement is discouraged. Creative-mode or equivalent non-vulnerable personnel are exempt from anomalous influence but must still avoid unnecessary observation to prevent collateral exposure of nearby subjects.

Description:
SCP-312 is a large, semi-translucent gelatinous organism that typically remains suspended at approximate cloud altitude. In its dormant state it is visually similar to ordinary cloud formations and exhibits minimal independent movement. SCP-312 does not initiate hostile behavior unless it is being directly observed by a living subject within roughly 72 meters horizontally and up to 285 meters vertically.

Upon sustained visual contact, affected subjects experience progressive motor impairment and reduced physical capability, accompanied by a strong directional pull toward the instance, comparable to localized high-velocity wind. SCP-312 will then drift laterally while maintaining altitude, positioning itself above the observer. If the subject moves under solid cover, the effect ceases and the instance typically returns to its prior location. If the subject approaches within approximately 5–6 meters, SCP-312 descends partially, ensnares the target with tentacle-like appendages, and attempts asphyxiation.

Natural manifestation is rare and occurs more frequently during rainfall or thunderstorms. Instances do not despawn under normal conditions and may react to observation by non-human organisms as well as personnel.

SCP-312, Atmospheric Jellyfish

A cloud-height entity that stays passive until you look at it. Looking applies Slowness and Weakness and pulls you toward it; get under cover to break the effect. Get too close and it grabs and suffocates you. Spawns rarely (more in storms), max 4 in the world, never despawns. (/gamerule doatmosphericjellyfishspawn false to turn it off) Creative/spectator are safe. Requires GeckoLib.
