The island of Nalcott embodies a twisted, post-apocalyptic wilderness in Once Human. Here, Deviations run rampant, spreading throughout the region’s various biomes. Once monstrous threats, these “creatures” can be captured and synced to serve as valuable allies in the field or at the base. So, keep reading to learn what Deviations are in Once Human, along with their effects and locations.

What are Deviations in Once Human?

In Once Human, Deviations are mythical creatures known as the spectral fauna of Nalcott remade by Stardust. Meta-humans can encounter these entities in the wild, either from defeated enemies or within containment units. Capturing a Deviation in Once Human is straightforward, as PC users need only press the “F” key (by default) to secure one. Each failed apprehension increases the capture rate, with this improvement reducing when trying to obtain high-level Deviations. Failure to secure a Deviation four times will make it run away. Note that each Deviation falls under one of three distinct yet vital purposes: Combat, Territory, and Crafting. Combat Deviations act as loyal companions in the field. Territory Deviations, such as the Logging Beaver and Electric Eel, help automate the resource economy at the base. Meanwhile, Crafting Deviations, like the Atomic Lighter, produce unique materials that can be used for various purposes, including crafting Whims.

Choose the right Deviation for your combat, territory, and crafting needs. Select from a broad range of Deviations to secure, such as the weakspot-marking Butterfly’s Emissary to the resource-automating Logging Beaver.
