Place it just before the moment of failure in a boss or raid edit, then follow it with a jumpscare scream once the trap closes. An alarm or enemy-spotted cue works just before it, setting up the threat so the payoff lands in sequence.
Über diesen Sound
This is a short, roughly five-second villain voice line in which C'Thun delivers the threat "Your heart will explode" in a slow, deep and menacing tone. It feels tense and ominous, like a boss warning delivered just before a fight turns against you, with a cold confidence that makes the threat land harder. It comes from World of Warcraft, where C'Thun is the ancient boss behind the line.
