Oh wow. That's a nice SOJ, sir. Keep rolling. You'll get it eventually.
It's very good as is, but not if he wants a socket to put a legendary gem in there. Then he loses all that crit damage. Decisions, decisions.
Yeah, the Energy Twisters deplete AP very quickly, especially if you put it on your left mouse and accidentally cast it like I do. I don't think the build is very active though apart from the resource management. All you're doing is moving around casting Hydras. Blizzards and Twisters and let them tick away health.
Yeah, the big problem with the build I told you about is the skill slots. I put Black Hole on left click and Twisters on right click specifically to avoid what you're talking about. I get easily confused between buttons.
I picked up a Light of Grace a few days ago and I much prefer this playstyle. Mobs just melt on T1 (playing on HC), since Black Ice does an insane amount of damage. I'm also using Frost Hydra with the Magistrate, which gives me an extra skill slot, basically. I often position myself in such a way so that the Frost Novas keep the mobs stationed and Black Ice can rack up the damage. I also use Black Hole with the cold rune for the cc and to maximize damage.
Just need to find an Azurewrath. ^^
Nice. How high can you farm? I hear cold and lightning are useless for high-tier Greater Rifts, and that essentially it's fire or bust, sadly.
