They have tried countless things- Anti-matter, reality warping, history manipulation, physics manipulation, ultimate poison/ultimate acid, higher dimensional manipulation, deals with the devil, other eldritch horrors, absolute storage, etc.

In fact O'Death is the only time 682 has ever been confirmed to be dead.
