You can lower/mute the critical peril noise

[Ethical Lune]

I just figured this out today so I'm probably the slow one here but just thought I'd say for anyone who doesn't know so you can avoid a few headaches.

Go to Options>Interface(not Audio for some reason?) and Peril FX Intensity, lower it to whatever you prefer and boom, Psyker is now much more tolerable to play.

Yep went down to 0 until they get more perils SFX. You hear all of them in 1 minute of gameplay anyway.

I was using a mod for that. Thank goodness it’s an in-game setting now. Thank you for sharing.
