Are you tired of tabbing and dotting everything with Shadow Word: Pain? Well now you can also do 2 in 1. I included Vampiric Touch as a modifier, once you are done spamming in normal form (Shadow Word: Pain), hold any modifier key and it will do the same with Vampiric Touch.
There you have it, 2 for 1 folks
