My gear isn't that great at the moment, so I've only been running expert -> Torment 1. Really lacking on most every important piece like resists/hp/LoH as well as damage, prefacing that as the build of the team is very strong.

This is the build.

Swap out Elemental Exposure for Cold Blood on the remaining characters. Also swap out Magic Weapon Ignite for something else if you want too.

I'd like to be able to zip around the map more using Teleport, but it's no where near as good as Dashing Strike.

Essentially with this build you hold down left click for Electrocute, spam Frozen Orbs and have the same key round robin Black Holes, and.. just sit there pumping out the damage. Magda was propbably the most hilarious fight so far. All of her terrible spells she uses, just get sucked into the black holes. Same with the Act 5 boss that uses those red slugs, it consumes those as well.

It simplifies encounters so much, it'll be hard to swap off of it.
