theorycraftish 2.5 ELE CoC ground slam tri-element

Hello! Before I start, a little about me if you care, I'm a first time poster (please forgive if the thread looks like a pile o' poo, I don't know how to make them look fancy), but I've played since before act 4 was released, and I'm far from pro. I did look through the forums (briefly) if there was anything about posting builds and what not and didn't see anything so I went for it.
I prefer to play HC because I'm a glutton for punishment and self abuse, and games aren't fun unless they hurt.
I've never made a CoC build, almost always play melee builds, and haven't beat the game with a witch yet and it's needed for an achievement. Please read it all before replying, any feedback is welcome (if you have nothing nice to say, at least make it constructive), but I'm most likely sticking to this build until completion, unless you have a very good reason to go another way. At the time of writing this, I'm in my 40s, still fire storming into the future, so it's semi theory craft.

Why elementalist?

Well were doing all 3 elements, and CoC!

Liege of the Primordial gives an extra golem, so that could be 2 ice golems which give 100% bonuses (40-60% increased crit rate and accuracy each) and picking up global crit chance isn't easy for witch

Paragon of the Calamity is great offense and elemental resistance (on HC, you can never have enough forms of defenses)

Pendulum of Destruction and Master of Discord are great offense, no reason to not have.

GEAR:
I have built this with no unique items in mind, of course something like taste of hate is always nice to have but otherwise, I'm banking on master crafting and alching gear. Looking for mostly str/int gear (armor & ES). Currently using have a Vagan scepter to eliminate the need for accuracy, which helps with crits.
Never been a fan of Voll's Protector, the power charges are nice but it has terrible stats. I found some Repentance gloves that have no spell damage loss, and am going to see about working them into the build.

CHEST SOCKETS: 3R-1G-2B
I have a 6l in mind, in it will be ground slam - multi strike - CoC - firestorm - storm call - Glacial Cascade

the 3 spells and ground slam scale well with AoE area and damage, storm call's delay between casting is ignored by the mechanic of ground slam, but will only be cast once on a single mob.
I'm aware glacial cascade is cold converted from physical damage done so the cold damage may not be great but GC has the ability to hit mobs multiple times, and with all the increased spell and ele damage, I'm sure it will still be good.

as far as boots/helm/gloves i only filled out 2 of these, so the 4th is open to input! but you'll need the 2 mentioned to look like this: 4B & 4R

the 4B item:

blasphemy-assassin's mark-discipline-enlighten

Assassins mark gives mana and hp on kill, increases crit damage and chance to crit, as well as power charges on kill. everything youd want in a CoC build.

Discipline is amazing ES, not sure why you wouldn't run it.


enlighten for obvious reasons, reduce mana reserve, as we will have MoM because it's essentially 30% damage mitigation from mana, so we'll want that mana to be available.



the 4R item:

CWDT - immortal call - increased duration - vortex

this will help you escape death (hopefully). With no real idea of how to generate endurance charges, the vortex chill and with increased duration on IC to C.Y.A!

the other 4L item is up to you, but I'm looking at ice golem (maybe 1 ice 1 fire), and minion gems to support it, maybe CWDT to not have to deal with bringing them back so requently.

3 link items youll need to look like this: 1R/2B


the 1R/2B item:
lightning warp - less duration - faster casting
this is your movement, feel free to go with some flame dash set up, I prefer this.


gems:
health or ES, attack speed, crit chance, elemental/spell damage. in that order


LEVELING!!!
firestorm your way to 60, like just about any mage build. all stats should be listed on the left in the links.
