Place it at the very end of a boss-fight edit, after the final hit lands and the screen settles. Open with the Inception Horn Sound Effect to build tension, use the Enemy Spotted Sound Effect when the boss appears, then let this fanfare close the sequence as the reward moment.
About this sound
This nine-second orchestral fanfare erupts with brass and strings in a rising flourish after a huge miniboss falls in Dragon's Dogma. It feels relieved and heroic, turning the exhaustion of a long fight into pride. The cue comes from Capcom's 2012 action role-playing game, where short musical stings mark major kills.
