I made a Lore-Based Unknown build. What do you think, and how can I improve on it?

(okay, so something completely ate my previous attempt to post this, so I'm trying to be more succinct. If you have questions or need clarification on my choices, feel free to ask)

Perks:

• Insidious: Pretend to be a Hallucination and lure people in when they try to dispel you. This is the closest way I can use Unknown's ability to mimic the voice and appearance of past victims to lure people in
• Mindbreaker: Nothing about the Unknown can be good for one's mental state, but the important part is the Blindness effect. Under Blindness, when a survivor is downed and hooked, if their allies aren't paying attention, then that survivor is basically gone without a trace.
• Monitor & Abuse: The unknown is a very methodical predator, keeping its distance, luring people in, and even when its prey is cornered, it'll take its time to build up the tension before the big attack.
• Alien Instinct: This one's the most replaceable perk on this list, but it has things I like. The name can reference one of the Unknown's potential origins, and if a survivor is injured and far away from you, that means they escaped: They know about the Unknown, so they are targets of the Unknown.

Add-ons

• Victim's Map: People who go investigating the Unknown, become Targeted by the Unknown. While most add-on's are pretty take it or leave it for lore based builds, this one works so well thematically that I'd say it's as important as the perks.
• Sketch Attempt: A survivor under the UVX's Weaken effect hears the Unknown's voice as being a normal person's voice, without the distortion effects. Presumably, the UVX's venom is part of how the Unknown can mimic or deceive its targets, that it alters their perception somehow. So the UVX applying Oblivious would make sense in this regard

And that's what I have so far. I'm pretty settled on Insidious and Mindbreaker for this build, but the other two, especially Alien Instinct, I'm not quite settled on, so if anyone has any other recommendations or ideas for this build, I would love to hear them.

thanks for reading my wall of text
