By slathering yourself in several different scents at the same time, on different parts of the body. Dance of Death on my wrist and neck, Umbra on one hand, Iago on the other...

Is it my fault that I've bought about 300 different imps/bottles in the last month and now I don't know what to do with them? (Yes.)
