Favored Host Each invidiak has a particular type of creature they prefer possessing, chosen from the following list: aberration, animal, beast, or any humanoid (such as dwarf)-in most cases, the favored type of target is human. When an invidiak uses possession against a favored host, the duration of possession increases to unlimited, and the effect lasts until dispelled or until the invidiak dismisses it.

Shadow Blend [two-actions] (divine, illusion) The invidiak Strides up to twice their speed. If the invidiak ends their movement in an area of dim light, they become hidden as long as they don’t move and the lighting in the area they’re in doesn’t grow brighter than dim light.

Unbodied Possession An invidiak leaves no body behind when using possession.

About

For most demons, possessing a creature requires a ritual, magic item, or condition, but for invidiaks, who lack a body, possession is akin to donning a suit of clothing. Known also as shadow demons, invidiaks are formed from envious mortal souls.

Rituals like planar ally or planar binding are typical for long-term ends, and summon fiend for combat applications. For planar ally, demons sometimes accept offerings that aren’t valuable if gifting them to a demon pushes the ritualist further into sin.
