I recently changed to Bloodbath over Avatar (I had in my head for some reason that Avatar was the best, so I stuck to it until I did more research) and I don't really understand how it works. My best guess is that you use it, attack with your normal rotation and somehow that adds to bloobath. I'm not sure what a 'special' melee attack might be considered as, either. Essentially 'some' of your attacks do 30% more damage, but in the form of a 6 second dot...every 'special melee', over 12 seconds.
Confusing. Any help?
