[1.3]--Megablast-- the unusual discharger / Windripper CoC build / Map focused

Carrasco_Santo thanks for remaking the tree, I'll update it on the build post :)

Oh thanks for the explanation on all the gems setup!
So I have to take this gems setup : Tornado shot - gmp - CoC - arc - freezing pulse - ice spear since I am on torment and I don't have voll's devotion?

Yeah, or item rarity instead of freezing pulse. It really helps to keep the map pool going and you drop quite a lot uniques (most of them are trash but once in a while you drop a ming's heart or CoE) :)

Ok thank you very much for your answers, I'm ready to drop :D

Thanks to Etup's build i Came with next way to play this build. It's really safe and I think 100% hardcore available.
You have to change a little bit your passives:

To have that extra piercing chance.
The gem sets are:
Aoe
Tornado shot - GMP - CoC - Ice spear - arc - Frost wall
Single target
Barrage - GMP - CoC - Fireball - Flame surge

It's really safe. Today I play with the rule "whatever rolls on the map - stays" (with only exception of ele reflect maps cause they are really slow to do) and I have to say that thanks to this combo I survived maps with -max resists + ele weakness or voulnerability + 30% monster damage and turbo mobs.
This combo feels really strong so far.

Hello, the build looks really cool. Just a quick question - it seems CoC triggered spells are the main source of damage. Then.. why not take those 28% spell damage close to Scion instead of, for example, piercing? Any math beyond my (rather poor) brain capabilities behind?

Sorry that took me so long to take a look here and reply.

Ok piercing is only for frost wall combo and it's neccessary to get more spells triggered. It's because the first shot from TS is ground targeted and have 100% piercing but the arrows that fly after that have normal status and the frost walls (and there is a lot of them) block all your arrows. As a result you trigger very low amount of spells and do far less damage.
It also helps your ice spears to hit more targets :)

how do u have the mana to use nado shot in the rich version when u dont pick up mana leech on the skill tree?

is this build atziri suitable ?

do you have any videos?
