Interesting to check combination Lightning Coil with new boots from Machinarium doryanui's delusion.

30% of physical damage will be lightning and i want to use Purity of lightning 25 lvl which made my Lighning max res is 87% with flask, and with ascendnancy i want to be immune to ailments, but although i take some nodes on HP, with jewels it's not so tanky and 300k dmg not so much. , i thought also about CI,LL versions, but i didn't make builds based on ES before. Mb tombfists with pair of abyss jeweles will be better.

And I have very much sockets for skill gems, I can make 2 6-links, but don't know what can be second except smite, totem?
Or try abyss items- boots, armor, helmet, gloves

So, I want to duiscuss about that build.

Main Weapon is Brain Rattler

For Main Gem Setup I choose:

Smite-Melee Phys Damage-Elem Damage with Attacks-Multistrike-Lightning Penetration-Conc effect\Inc AoE effect
