Well I'm sure it's hugely popular at parties and elsewhere outside of combat. Shall we give it 'earning money' rules like Perform and Profession checks, or would that be too depraved?

In combat, it kind of goes both ways. Hang on... Will save negates the daze effect, but what about the benefits? Can you make separate saves? If so, the Saving Throw line should be something like 'Will negates (harmless) and Will negates'.
