Put Kastsystem at the turning point of a fail edit, just before the reaction shot, then follow it with a Vine Boom or a SpongeBob Fail for the reaction that follows. Use one follow-up only, so the moment stays focused on the miss.
关于此声音
Kastsystem is a brief sound effect lasting just over a second, built around a single sharp burst that cuts in and out without a spoken line. It feels abrupt and attention-grabbing, the kind of quick jolt that suits a sudden reveal or a failed attempt. Its short, self-contained shape makes it easy to place exactly where a reaction is needed.
