This is mostly for Hunters and mages, i hope it can be an help.
It's actually quite easy to do this, all you need to do is that you have to combine tricks and then try them on Dr.Boom, You can find Dr.Boom in Netherstorm. So all you have to do, is to try di sine experimencents with it and then see how it works,
This was after our Raid tonight. so hope this helped you all
