THE UMBRA is a cloaked apex hunter world boss. It stays invisible until it is close, hunts the player who wandered off alone, and finishes with a cinematic devour.

• Cloak: invisible beyond 80 m, a shimmer inside 30 m. Looking at it breaks the cloak.
• Senses: it sees a front cone and hears gunfire, sprinting and engines. Ash or mud camo makes players harder to notice.
• Attacks: pounce, claw sweep, tail whip, seize, shriek, ink cloud, dorsal spike volley, shadow clone and shadow step.
• Weak points: crest, arm cysts, belly sack, tail (cut it off and it can never cloak again) and four dorsal cores.
• Phases: phase 2, flight at low health, then enrage. It learns from camping and flanking.
• Co-op: pull spikes out with E, break free with A / D, and teammates can free you.

Standalone: works with QBCore, Qbox and ESX. No ox_lib or database required. Core is escrow-protected, config.lua is open and fully documented. Exports and events for developers included.
