[2.3]The One from Tesla battalion (simple and stupid guide to aurora/mjolnyr tank)

+We are tanky. Braindead afk-tanky against most thing. Close to immortal against big packs even if you play with eyes closed.
+We have decent AOE clear speed. Clear half of the screen with one button press.
+"Easy"(t11 and below) maps can be cleared with minimal player input. And even less with CWDT+lightning warp.
+We can facetank Atziri without dodging, flasking and other nonsense.

-Our life is boring. We just walk and randomly spam left button. Sometimes right one. No kiting, no dodging, pots are there only to remove corrupting blood.
-Relaxing. Yes, it's bad. You can quickly lose your skill in our ranks.
-Bad single target damage. Bosses with high regeneration like Wasteland one can waste lots of time.
-Hard limits. Cause of almost zero player input most fights are simple gear checks. And when you loose them... you loose them.
-Can be so much more - there are lots of things that can be used, like endurance charges, "good" flasks etc. But I'm to lazy to use more than 2 buttons - mouse ones - and so they aren't. I will write about them, but don't use them myself.

Sorry, but equipping recruits can't be handled by poor funding, so you must bring you weapon and armour with you. And as bare minimum you will need.
1)Mjolnyr. Non-legacy one. It's even rather cheap - can be found for 1 ex.
2)Aegis Aurora - non-legacy too. Slightly more expensive - 1.5 ex.
3)Astramentis - 1.5 ex.
4)Repentance - 1 ex.
Mjolnyr is our heart, soul and spirit - with it you can fill the air with so much lightnings that any arc mage will cry in a corner.
Aegis Aurora ES regen on block with 75% block chance will make you invincible against small hits(less than 3-4 % of your armor after mitigation).
Astramentis is necessary evil for int and dex requirement of skills and gear, especially Mjolnyr and Repentance.
And, lastly, repentance will give 4-th link to Mjolnyr so the question "What's better for Mjolnyr - Iron Will or Lightning Penetration?" could be answered "both"
In other slots you need generic rare items with high HP, armour/evasion and strength. Most of resistances would be handled by passive nodes and jewels, so despite high str/life/armor price of rares should remain adequate.

There are two main skills - first for pack clearing and second for killing single target in time, that don't measure in eons.
First is Lightning Strike - remember that you can attack "empty space" with it to send waves of lightnings into enemies from good angle and position, where all hits will trigger mjolnyr and send even more electricity in the form of Arcs. This skill also dips as a ranged option against things we really don't want to come nearby - mostly those exploding kamikaze
Second is Molten Strike - it launch balls of magma around the target. Primary target CAN be hit by extra projectiles and so "pseudo-shotgunned" with mjolnyr procs from it. Average number of hits depend of target size, will write about it in depths below.
Important support gem worth mentioning is Life Gain on Hit - since both attacks usually trigger huge number of hits per second LGoH become way more effective that life steal - it's instant, it doesn't depend on damage done, so work even against immune target, it simply have greater value of hp/sec.




Other skills worth mentioning
Tempest Shield - since activating it "by hand" is too much work it should be linked with lvl1 Cast when Damage Taken - so it will activate after first non-blocked hit. Just be sure to have tempest shield be low anough lvl to work with lvl 1 cast when damage taken. If you have Improved Item Quantity.. you probably find nothing interesting in this guide, but anyway, you could link it with Culling Strike to Tempest Shield.
Reckoning and Vengeance - good skills that make counterattacks, which proc mjolnyr, apply curses with Curse on Hit and sustain if linked with Life Gain oh Hit. For latter better use Vengeance since it work on hits that you didn't block, which means they could cause some damage and healing will be right in when needed most.
There are also one important aura - Grace. With Iron Reflex it give tons of armour. Others should be switched depending on situation. Purity of Fire(or lightning) for Atziri and other heavy fire(or lightning) bosses. Purity of Elements on "Elemental Weakness" maps. Determination when in danger of high physical damage boss. And Wraith or dual Heralds when danger is low for high clear speed. Switch your auras depending on map.
Mobility skill of choice - I prefer Lightning Warp, but Leap Slam is fine too, if you are into that. I just hate jumping in heavy armour.

Nothing interesting even there. Till lvl 60 you can play like any normal tank with block and one handed mace. Sunder or some other melee skill of choice will carry you to 60. Build have good amount of life and block nodes so surviving till you can equip mjolnyr and aurora shouldn't be hard.
After that simply farm Dried Lake(1-st location in act 4 after you find town) till lvl 65-68 or so and go farm Crypt Maps. First they are relatively easy map for leveling and farming and second there can drop one important divination card - Celestial Justicar. Collect 6 of them and get 6-link astral plate. Drop couple alchemy and then of chaos orbs on it until it have decent stats and you are set. While really RNG dependant it's simple and cheap way to get a decent chest - most important of your rare items. Check all chest ans barrels in Crypt - they can drop card too.

1)Q- Why you use double arc? It's bad! Discharge is better.
A- It is. With Voll's Devotion and Romira. Voll is really expensive and give less stats so we need more int from tree and gear. And if you CAN afford Voll you, probably, know what you are doing are read guides only for fun, not for useful info. Also double arc is way better for those with bad PC, since discharge have too much graphic effects. And without Voll double arc is better since good rare ring is way better than Romira.

2)Q- Is this even a build? It's so simple it look like a work of Captain Obvious.
A- Yeah, I know. I warned you like 2 times.

3)Q- All your gear, passive tree and auras are defensive. Where does damage come from? And what is your DPS?
A-

4)Q- There are not enough info to be called a guide. Should be more detailed.
A- Yes, I know. It will be expanded soon. With screenshot and such. But this is written from work, where I don't have PoE to make those screenshots.

5)Q- You should really use Doryani's Fist, not Mjolnyr for a build under this art!
A- I wish I can, I wish I can...

I also use an Inutitive Leap (by the Templar) and Brute Force Solution to convert strength to int down by the Duelist
