quick little ref and some descriptions (It/any but it’s recluse disguise is a he which i will be using here for simplicity)

-He has his humanoid form that is used to blend in with the town, and a lleech like form that he uses to infect people, they are separate physically but controlled under 1 consciousness

-He can go an amount of time without a host, but it’s like a human holding their breath, like if the host is killed, it still has about 5 minutes to leech someone new and continue to live

-He is mimic like in the sense that he can imitate parts of his previous hosts from his main form, but not across them, like he can’t pretend to be the cannibal through the puzzlemaster but he can in his own pretend to be both of them

-He usually kills in his own body to separate suspicion from his host who actually needs to be innocent, but in a pinch he can control his host for brief periods of time

-It is fully sapient in terms of capacity for thought but more feral than other demons like how i see the vortox (being one of the most human like in my opinion), there is no need for deception or some big plan to take over the world or something, just an animalistic desire to hunt

-He can draw his energy and sustenance from his host like a leech would, but doing on,y this would cause the host to deteriorate faster, so to avoid taking too much before they can heal, it will also hunt and kill like a vampire would
