[2.2.2]Elementalist Mjolner: Life and armour - EE/RT - Getting a buff for 2.3!

Pendulum of Destruction adds 25% increased AoE alongside 100% increased elemental damage every 10 seconds for 4 seconds.
Paragon of Calamity gains 50% elemental reflect damage reduction(like we need it).
And the one I'm most excited about: Liege of the Primordial gets +1 golem and I will definitely be adding my flame golem back into the mix for a serious damage boost. 40% increased fire damage and 38% increased general damage(level 16 golem) sounds good to me!

With the Ascendancy expansion out now, let's talk about which class to choose and some of the options.
When you look at the classes the Witch offers, only one truly stands out: Elementalist. Pretty obvious since you deal loads of elemental damage. Occultist has nothing of significance to offer and Necromancer only has a couple nice attributes for a Mjolner build. My main focus when I mapped my Ascendancy tree was maximizing boss battles.
Very good bossing choices
Pendulum of Destruction: Why WOULDN'T you take this node? 100% increased elemental damage for 4 seconds? Yes, please. And the sweet part is, the cooldown starts when you gain the buff, so 6 seconds after the buff ends you will have it again. The smaller node before it is amazing too, 4% increased attack speed and 10% increased elemental damage, A+.
Liege of the Primordial: If you can sacrifice some physical damage mitigation to gain some serious attack speed, then do so because lightning golem here is an absolute beast. Since we use a high level CWDT setup our golem is level 16 and that happens to be the first level where it gains 9% attack and cast speed granted to players. Even better LotP grants 100% golem effect which ramps it up to 18% increased attack speed, which is a huge DPS boost. Of course, flame golem is still an option and if you feel this is better for you then go with that. Smaller node includes 10% elemental damage and 3% ignite, freeze, shock chance(boo).
Paragon of Calamity: With great offense you need a great defense and this can provide with a nice defense boost to elemental damage. Got hit by lightning/fire/cold damage? No worries, Paragon of Calamity with increase your lightning/fire/cold damage by 40% as sweet revenge and also grant you 8% lightning/fire/cold damage reduction for future hits(if they live long enough[which they dont]). I really like this node because a vast majority of elemental damage in this game is fire and lightning and those are your main offensive elements. Plus, they are your highest resistances and taking even less damage is amazing. This node is amazing for Atziri runs! Smaller node grants 10% elemental damage(again!) and 6% all resistances. All in all you gain 30% increased elemental damage at all times which is a really massive boost, especially for Discharge.

LEVELING GUIDE

This is a Mjolner build, so BiS.

Kingsguard is used to generate loads of life every time you discharge, and you'll discharge quite often so this is crucial to your survival. But this would be absolutely useless without...

...Voll's Devotion. Pretty standard for a Mjolner discharge build, you gain an endurance charge for every power charge consumed by discharge, which results in massive damage increase. This, too, would also be useless without...

...Romira's Banquet. For every non-crit hit you gain a power charge for use by discharge, rinse and repeat.

Devoto's Devotion makes mapping smoother with its increased movement speed. Attack speed is greatly welcomed and the dexterity is really nice since this build needs 142. It also gives great armour since we grab Iron Reflexes.

Saffell's is great for resistances and helps mitigate reflect and increases our spell damage. Cannot block attacks doesnt really affect us much and the spell block is really nice.

The rest of your gear should focus around filling remaining resistances and high life rolls, 30% movement is nice since I personally do not use a movement skill. Use these pieces to also fill in any attributes you need, mainly dexterity and intelligence.

A 6 link chest is not truly required as you would only be losing LMP and 10% attack speed(for quality LMP) also the enchant I have on my boots is really nice for mapping. Not sure if I'll change it anytime soon unless I see something better.

You'll need either a caustic Eternal flask or a seething Divine flask, depending on what you like to play with, either way they need to be "of staunching" for corrupted blood and bleed. These are for emergencies. Quicksilver for movement and everything else is up to you, Atziri's Promise is a good option for more damage against tanky bosses but I found it unnecessary and no longer use it. For the more currency inclined Vessel of Vinktar is by far the best flask for this build as long as you have a grounding flask to back it up.

Weapon
Discharge->Arc->Controlled Destruction.
Since we take EE Lightning Penetration is no longer required. Controlled Destruction is better than Iron Will as it adds a more multiplier and is overall superior because it is a blue gem which allows us to swap in LP for 80% lightning resistance maps. ARC MUST GO AFTER DISCHARGE as it will proc EE and result in Discharge doing less damage.
Ball Lighting is a really good alternative or permanent gem. It lands more hits which results in having max power charges most of the time, very good to use against map bosses and Atziri.

Chest
6L: Molten Strike->Multistrike->Faster Attacks->GMP->Fortify->LMP(Bosses)/Lightning Strike(maps)
5L: Just drop LMP and you're still a murdering machine.
Since we do not use Blood Magic a mana gained on hit jewel is required and solves any mana issues.
Lightning Strike procs Mjolner like no ones business but can be a real pain on your computer. I usually use it on smaller packs. It's also really good to use at range for rippy maps and let Arc do its business.

Auras
Purity of Lightning->Purity of Fire->Arctic Armour->Enlighten(level 2-4)
Blasphemy->Enfeeble->Enlighten(level 2-4)
Our main aura setup is PoL-PoF-Enfeeble. For curse immune maps we switch to Arctic Armour.
Purities help mitigate as much reflect damage as possible and blasphemed Enfeeble reduces incoming damage by quite a lot and is much better for mapping and bossing than Arctic Armour since you do not need to stand still and Enfeeble reduces the damage before any other mitigation happens as long as the enemy is cursed.



Cast When Damage Taken
I run two separate CWDT set ups: one defensive and one offensive.
Defense set up: CWDT lvl 14->Immortal Call lvl 16->Molten Shell lvl 18->Increased Duration. Since we almost always have 3-5 endurance charges a high level Immortal Call is a great defense mechanism lasting anywhere from 2 to a little over 3 seconds.

Offensive 1: CWDT lvl 14->Summon Lightning Golem lvl 16->Blood Rage lvl 17->Enhance
Your Golem is one of your best offensive attributes. Hooking it up to CWDT takes the time you'd have to take to recast away, which is great for tough bosses. When linked with enhance your Golem becomes more tanky and is able to survive until the next cast. Having an automatic Blood Rage is great for boss fights when you need that extra attack speed and enhance makes it even more potent.


Gems to quality:
Discharge - increased AOE
Arc - shock chance
Controlled Destruction - increased spell damage
Faster Attacks - increased attack speed
GMP - increased attack speed
LMP(for 6L) - increased attack speed
Summon Lightning Golem - increased life and damage
Blood Rage - increased attack speed

Throughout the tree we pick up 5 jewel sockets, jewels are so powerful and should be implemented in every build when possible. They can really push a build to its maximum and help optimize damage or defense.
I focused on attack speed and damage throughout my jewels. One +2 mana gained on hit is all you need to sustain mana

I cannot remove Intuitive Leap to post here.

Unbuffed

Basalt and Jade

20q LMP, Lightning Golem, and Blood Rage

I can efficiently kill Atziri and have completed all tier 12-15 maps excluding Core. I have not attempted Uber Atziri yet and am very hesitant since I have never attempted her with any build.

Wasteland Voll kill
Shipyard boss kill
Double boss Overgrown Ruin
Deathless Atziri This is a terrible video with lots of latency spikes.
Waterways boss kill
Shrine boss kill More terrible latency
