Augmentations are very similar to worn magic items, except you have far fewer slots and they're much more challenging to swap out. They often confer benefits like ancestry and heritage features, such as new movement speeds and senses. Be aware that 1st-level augmentations can be selected at character creation using options such as the
Cyberborn background. The only augmentations that don't use slots should be apex items and augmentations such as
moodskin that confer little to no mechanical benefit and are usually level 0.
