[1.3, HC BL]Multi-Curses Aurabot (Level 100 Rank 3)

Helm: Alpha's Howl
Best in Slot. This allows us to fit in more auras and gives a serious boost to 3 of them. Freeze immunity is really appreciated as well for Low Life or CI characters.

Chest: Shavronne's Wrappings or Solaris Lorica
Best in Slot and mandatory. If you can't afford Shavronne's Wrappings, Solaris Lorica will do just fine. It will result in a loss of up to 2'000 ES, however the build boasts a large ES pool to start with.

Gloves: High ES Rare
Pretty straightforward, just pile up as much ES as possible and some Resistances.

Boots: Rainbowstride or High ES Rare
Pretty straightforward, just pile up as much ES as possible and some Resistances.

Shield: High ES Rare
Pretty straightforward, just pile up as much ES as possible and some Resistances.

Belt: High ES Rare or Batted Breath
Pretty straightforward, just pile up as much ES as possible and some Resistances.

Weapon: The Supreme Truth or Ephemeral Edge
Get The Supreme Truth for the increased Gem Level and for the increased Experience gained, or Ephemeral Edge if you want more survivability (its bonus is equivalent to 7 or 8 passive points spent on ES nodes).

Amulet: Eye of Chayula
Best in Slot and mandatory. Stun Immunity is very appreciated as Low Life or CI. Ideally, get one that is corrupted to +1 Curse.

Rings: Doedre's Damning and Elreon's -8 Mana Cost of Skills
A rare ring bought from Elreon with -8 Mana Cost of Skills allows you to run skills on Life despite having almost all of it reserved. Ideally, craft it to get 20% ES on as well on it.
Doedre's Damning allows for an extra Curse to be used. Potentially, you can replace it with either another rare ring or a Perandus Signet for extra experience.

Chest BB-BG
4L: Arc/Ball Lightning, Curse on Hit, 2 Curses
5L: Arc/Ball Lightning, Curse on Hit, 3 Curses or 2 Curses and Faster Casting or Spell Echo or ?
6L: Arc/Ball Lightning, Curse on Hit, 4 Curses or 3 Curses and Faster Casting or Spell Echo or ?

Helm 4L RR-BB
Reduced Mana - Purity of Fire - Purity of Lightning - Discipline

Gloves 4L R-B-GG
Reduced Mana - Hatred - Wrath - Grace

Boots 4L RR-GG
Reduced Mana - Purity of Ice - Vitality - Haste

Weapon 3L
Either Leap Slam - Faster Attacks - Random slot or Increased Duration - Vaal Discipline / Haste x2

Shield 3L RRR
CwDT - Enduring Cry - Immortal Call

Note the following:
- Obtaining four off colors on Solaris Lorica could be troublesome;
- We could put Leap Slam - Faster Attacks in a 4L next to Reduced Mana and an Aura, and put 2 Auras and Reduced Mana in the weapon if running The Supreme Truth to benefit from the +1 to Gem Level of the weapon;
- Purity of Lightning/Fire/Ice need to be Level 21 for them to give an extra 1% Max Resistance when put in Alpha's Howl, so don't bother until then and don't hesitate to swap Auras around to make coloring your gear easier.

Stat Requirements
153 or 157 Dexterity to run Level 20 or 21 Grace and Haste. Pick 2 Dexterity Nodes and have a spot on gear for Dexterity to achieve it. Not a big deal if you don't.
153 or 157 Strength to run Level 20 or 21 Vitality. Have a spot on gear for Strength to achieve it. Not a big deal if you don't either.
A bunch of Intelligence, not an issue here.

Energy Shield
At level 90, you should be sitting at over 8'200 ES for the Shavronne's Wrappings version and over 7'000 ES for the Solaris Lorica version. Better gear and skill points earned past level 90 spent on ES should allow for serious improvement to these numbers as well.
Here's the math behind it:

Resistances
Your resistances will sit at 82% Fire, Lightning and Cold and -60% Chaos. If you get your hands on Level 21 Purities, you can reach 84% by placing them into Alpha's Howl.
With just 62% Fire, Lightning and Cold Resistance required from gear, capping your Resistances will be very easy between your Gloves, Boots, Shield and Belt not to mention the Cold Resistance on Alpha's Howl and Lightning Resistance on Shavronne's Wrappings.
Here's the math behind it:


The Auras
All Auras

By default, we run:
Discipline
Grace

Vitality

Haste
Hatred
Wrath

Purity of Lightning
Purity of Ice
Purity of Fire

These 9 Auras reserve 98% of our Life(Aura Calculator).

The Mana Costs
The idea is to run a Level 1 Ball Lightning or Level 16 Arc supported by Curse on Hit and the desired Curses.
Given 98% of our Mana is reserved for Auras, we're left with barely any Life unreserved thus the use of a ring with Elreon's -8 Mana Cost for Skills. This would have to be tested though, as in effect a Level 1 Ball Lightning could potentially work without needing the ring.

As of 3 weeks into Bloodlines, the build could be done for as low as a few Exalts. A more realistic figure would be 8 Exalts with a 5L Solaris Lorica. a 5L Shavronne's Wrappings version would run you 25 Exalts or so.
Here's the math behind it:
