I'm having a hard time finding information on the mechanics behind Hack and Slash. My problem is that I'm having to temporarily use a dagger in my OH to keep my Exp capped. I'm going from a 1.5 speed sword to a 1.4 speed dagger of the same item ilevel. I understand that my dagger will not benefit from the 5% chance of an extra swing from Hack and Slash but my main question is about how Hack and Slash actually works. Is HaS on any kind of ppm model? Flat percent chance? Flat percent chance with an internal CD? I guess I'll have to go to the spread sheet to see if the fast OH will make up for losing the extra hits with extra poison and Combat Potency procs. Thanks for any insight you all might have!
