About this Mod

the_obsessed_title

Welcome to The Obsessed.

A mod by Vllax, the creator of Arthropod Phobia Expansions, with original direction from IDK Someguy. 

The Obsessed is a mysterious entity defined by one thing: it finds you fascinating, but in a way that is twisted and dangerous. Though it may initially seem friendly, its mood can shift without warning, and when it does, it will make your life a living nightmare. It hides many secrets that will be revealed in coming updates...

A complex modular entity that truly feels as though it has a mind of its own, with countless advanced mechanics that will continue to be expanded upon drastically in future updates. You can find a spoiler with more information at the bottom of this page.

Shaders and dense biomes, like the redwoods from biomes o' plenty, are recommended in conjunction with this mod.

More info + MC versions! ⚠️
