Place this clip at the exact frame of the failed attempt, after the build-up and before the reaction shot. Follow it with the nope meme sound for a second refusal, or lead in with an enemy spotted alert when the attempt starts in a game edit.
Über diesen Sound
This clip is the short Diablo II voice line 'Not Here. Not in Town.', a flat spoken refusal lasting just under three seconds. It lands as firm and a little deadpan, turning a simple no into a final answer that feels both serious and funny. It comes from Diablo II, where the line plays when an action cannot be used in town.
