Heavy Summoner Arc Witch Guide [ Video Included ]

I am still playing arc summoner, my current build for 1.2 update, build:

* almost maxed minion talents;
* 168% increased maximum life, 2.8% life regen per second;
* 180% increased mana regeneration rate;
* +10% chance to block spells with a shield (currently 37% block rate);
* +18% chance to block attacks with a shield (i have 52% block rate with a 30% base spirit shield);
* +230% spell damage combined;
* +40 to dexterity and +252 to strength.

In 1.2 update Arc damage was nerfed by 20%, so need a quality arc gem in a +2 lightning gems wand. Since arc now chains 6 times (was 2 times before) elemental proliferation is no longer needed.
Also since ranged type monsters health and damage were hugely nerfed - i switched to melee spectres (except undying incinerators, whose fire trap still does good damage).
