3.2 - AssaMancer BV MoM Uber Lab (Budget to Endgame) The Queen of Blades v2

6:38:00 Kitava 10
15 hour first uber lab

This build is designed to be a boss farmer that can complete a lot of boss content with little gear. This build also scales well with gear so the survivability and boss killing speed gets better over time. This build is designed mostly around farming Uber lab; however, would also function great as a boss clearer to complement a fast clearing mapper.

When you think about Uber lab you really have two separate specialties: killing Izaro / Argus with a low chance of failure and moving through the lab as fast as you can. We use two weapon sets to achieve these goals
Killing

Moving
+ Leap Slam-Faster Attacks - Fortify to navigate the lab.

How I landed on this build
In 3.1 I started off with a Necromancer Blade Vortex build and it was strong, incredibly so. I felt super tanky and did good damage. When I saw the Necromancer changes (-50% offering) I was sad, until I realized that the Scion basically got the same defensive buffs that the Necromancer has now plus the ability to get more damage. When I switched over my current Necromancer to a Scion in PoB I was able to squeeze ~50% more damage out of the same gear, with only a mild loss to block. So Scion it is!

As a Mind over Matter user we want to make sure that we have at least 43% of our max life as unreserved mana. (Supporting math found on wiki)
In order to maximize our survivability without breaking the bank we are going to use Aurumvorax at first. This will give you 40-60% all res (don't break the bank going for 60%) which is a big deal! In order to be resist cap you need 135% in each of the 3 elemental resists, so 405% resists. Since Aurumvorax is going to provide 120-180% of this (~42%) then you're free to buy rares with higher Life/Mana but crappy resists. These items will be SIGNIFICANTLY cheaper than rares with high Life and high resists, let alone ones with Life/Mana and high res.

Stat Priority on Rares
1 - Maximum Life
2 - A single elemental resist (any resist you're not capped on)
3 - Maximum Mana
4 - Dex / Strength
5 - Extra resist

oh by the way you need a good amount of Dex (151/155/159) for level 19/20/21 Blade Vortex.

Please note that only Energy shield bases will have Mana on them. Armour and Evasion are generally worthless for this build, don't bother stacking them on your gear. Until you have pledge of hands you will likely not have enough mana to cover the Life * .43 ratio. IF you are over on mana without Pledge then you're likely low on life.

Side note: Amulet / Ring
You can score a LOT of resists on a single piece here. I would generally start with a medium life, HIGH res ring and amulet. Then eventually move towards an amulet with more damage mods, you can get the following on amulets:
Global Crit Multi / Global Crit / Spell Damage / Cast Speed

If you are leveling this as your first character then the tree is going to be slightly odd as I decided to start with Sunder. You should likely switch over to BV around level 40 with the following links: BV - Onslaught - Controlled Destruction - Conc Effect. You could level as BV from level 12 if you want or if you have twink gear, this is just not the route I took.

You'll need gear that has DEX on it in order to level your gems smoothly, although taking nearby +30 DEX nodes is okay. You’ll also need STR (heavy belt good option) if you’ve decided to also go the sunder route. If this is your first character of a league you may need friends / the market in order to obtain gems. Otherwise, if you have completed the gem vendor quest in Act 6 you should purchase the following:
Required Gems

Passives

Ascendancy Order

Fancy Leveling Gear

When you start Uber lab I would recommend being at least level 70 and having a 5L Blade vortex (Level 19). Decoy totem and a spell linked to Culling Strike Support is also EXTREMELY helpful at this phase. Make sure the rest of your gear has life and mana with a bit of resists. Aurumvorax can carry a lot of the resists (especially if you buy a good roll) so you should be able to buy higher life + mana items than normal since the resists will be middling. Generally, before I do my first Uber I'll do a test Atziri run or two to check the damage and survivability.

Once again I cannot state how important Decoy totem is when starting off the lab. With proper decoy totem use, its possible to take barely any damage with Izaro, don’t try to just face tank him. Our first and primary defense layer is that Izaro is busy walking over to decoy while we burn him down.

That was exactly the first character that killed Uber

Flasks


I would highly recommend ignoring Argus and skipping/bypassing extremely rippy Izaro mods (Charges|Conduits|Essences|Gargoyles are generally more dangerous). I would also EXTREMELY recommend hitting as many Darkshrines (that are somewhat reasonably easy to get) since they are always positive now and can give you permanent shrine mods that can make the lab a cakewalk. (e.g. 100% crit, take no damage)

I started off in Uber with an Aurumvorax and a shield. I upgraded my gloves / boots / helmet / ring / amulet with the following priority:
High Life
1 Single Res (Craftable even)
Mana
Dex / Strength
Once I was able to remove my Aurumvorax and shield I bought a Pledge of Hands and used a Jewellers Touch prophecy to 5L it. Then I shopped for a new chest armour. I looked for something that had as much life as possible with a bit of resistance to cover my 1 res that would have been short otherwise. I landed on a rare chest with ~140 flat life and 40 res for ~4 chaos. Then I farmed farmed farmed until I could afford a Kaom’s Heart and upgraded a couple rares to cover my resistances. After this point I stopped spending any money on upgrades until I obtained a Headhunter.

At this point you should be able to comfortably defeat any Uber Izaro combination with a little bit of Decoy Totem tactics. If you want to keep improving your gear, in case you want to go farm harder bosses, you can get better rare items, maybe even a fancy shaper/elder amulet.
