There’s nothing wrong with adding a sound effect to the bolt and playing it when spawned. For the character, it depends on what you want to achieve. If you want to add variations to a triggered sound effect like swinging a sword, you can do that by making an audioclip array and calling a random sound effect from the array when the action is done, You could also do this with your bolt if you want to have a variety of sound effects to play when it is spawned, like this.
