Noose

A floating noose heads your way, its infinitely long rope extending into the skies beyond the reach of human eyes.

The Noose is persistent, perpetually seeking to fulfil its one purpose, one goal: to hang you. Instinct of 3 is required to spot it descending upon you before it loops around your neck, and begins to pull you up. Because it is just a rope, it is easy to cut through, provided that one has a sharp tool at hand – but if caught empty-handed, you will meet your end and hang for as long as your body holds together. When cut, the remaining part of its length is left hanging from the heavens, and the loose noose can be repurposed as a short rope.
