Personally, you’re kind of wasting a perk spot using Insidious. You really should always be doing something, and having to stand still to get no Terror Radius is only good if you camp people, which I advise against.
They just changed Bitter Murmur and that one is pretty useful on most Killers. It’s okay on Freddy, but not the best since Freddy is already good with seeing auras in the dream world.
Yeah Devour Hope is a Hag teachable perk and is great if the Hex isn’t found by Survivors.
I recommend BBQ & Chili (Leatherface teachable) because it’s great for everything. Basically whenever you hook someone the auras of the other Survivors are revealed to you for 4 seconds if they’re further than 52/46/40 meters. You get bonus stackable bloodpoints for each Survivor hooked for the first time. If I’m running Devour Hope I’ll make sure I have BBQ on because I can hook someone and then takeoff for the furthest person I see so I know I’m heading toward someone, I’m not camping the hooked person, and I’ll get a token since I’m moving far away when they get unhooked.
Hag’s other teachable Hex: Ruin is also a good option for Freddy because it slows down the match until they find the Hex. Ruin basically fucks with generators by having it regress instead during skill checks. Freddy is such a late game Killer that this can help you get some early hooks before gens get repaired.
Never run the Overcharge (Doctor) perk on Freddy. I’ve seen people do that and it’s embarrassing. NOED (No One Escapes Death) is a decent perk choice for just about any Killer, but you don’t want to run it if you’re already running a Hex perk. NOED Hex only activates once the exit gates are powered; it picks a dull totem on the map at random and becomes a Hex so if there aren’t any more of those left because Survivors cleansed them then it won’t activate. If NOED 3 is activated then you can one hit down Survivors. Pretty powerful.
