[CI FRENZY Splash] Zealot's Oath + 7 Frenzy Charges, Marohi Erqi+Blood Dance+Shavronne's Revelation

The main point is the use of Zealot's Oath, Frenzy charges, and The Blood Dance boots to achieve massive ES regen. By getting the 3 Frenzy charges on the passive tree and helping Kraitlyn in Merciless, you can achieve 7 Frenzy charges. By using the recently released Blood Dance boots alone, you can achieve 7% ES regen. It is possible to reach 10%+ ES regen with this build and, depending on your gear, 7-8k ES. That's 700-800 ES regen per second. Just try and get that much life regen. Are you interested yet?

P.S. Originally when I proposed this build, I claimed that 1k ES regen per second was possible. That was when I was considering using 5 Endurance charges and getting the "Life Regeneration per Endurance Charge" to get an additional 1% ES regen. However, it costs quite a few points to get there and it's not really worth it, so currently the max possible % ES regen is 11.07%. (I am aware that the Templar tree has a 1% life regen node, but it requires sacrificing a point for 6% increased maximum life. This might be worth it though.)
Calculation: 7(7 Frenzy charges) + 2.3(Golem's Blood cluster) + 1.77(lvl 20 Vitality w/ Inner Force) = 11.07
If you want to achieve 1k ES regen per second, you need 9033 ES.
If you have 12.07% ES regen though, you need 8285 ES (which some players have achieved) to achieve 1k ES regen per second.

UPDATE: I've calculated what is necessary to use Shavronne's Revelation (you can find the numbers in the "Gear" section. If you're able to use the ring, you can achieve 13.5% ES regen with 7 Frenzy charges, the ring, Golem's Blood, and the life regeneration node in Templar tree. With 7407 ES, you will have exactly 1k ES regen per second. With 6k ES, you will have 810 ES regen per second. You probably don't have enough mana to cast Vitality unless you remove Determination (I would never remove Purity).

P.S.S. I also felt like it was high time that someone made a viable build using Zealot's Oath. I searched builds that incorporated ZO and all I could find were troll builds (apart from low life RF dual spork, which is pretty much the only popularized one). This is probably because ZO wasn't a very good idea--especially for melee--until The Blood Dance boots rolled around. Well, guess what? THE AGE OF VAAL PACT IS OVER, AND THE AGE OF ZEALOT'S OATH IS HERE.

CI builds are quite dominant at the moment because they are able to achieve higher amounts of ES than life builds can achieve HP. You've probably seen streamers with 7-8k ES, but of course such numbers are usually only achievable with top tier gear. While it is possible to do the same with life, it is much harder. Although you can get higher % life regen on life builds, especially when they use The Blood Dance boots, their total HP pool often is less than the total ES pool of CI builds.

It is possible to get 8k life if you have Kaom's, but of course this is not feasible for most people (and Onslaught doesn't have Kaom's). Someone with 8k life and 15%+ life regen (with The Blood Dance boots) would have 1200 life regen per second. However, since most life builds max out in the 5k life range, you'll only get 750 life regen per second.

Don't get me wrong, VP is great. I just wanted to make a viable build that used ZO instead. There are some advantages/disadvantages though.

Advs:
- ZO allows you to regen ES just like how life builds regen HP. This is good against DoT damage like burning or bleeding and reduces the number of times you have to back off from a mob or boss to wait for your ES to recover.
- ZO allows you to regen ES while you are not leeching. There are times when you cannot leech ES using Ghost Reaver because you are not close enough to damage mobs, you are stunned, or you are frozen (among other things). Sometimes you can die really quickly without any time to escape and wait for your ES to recover by itself. Sometimes you almost get one-shot by bosses and have to run, but you're still taking damage and not recovering any ES. Who stays around to leech ES when you're almost dead? Exactly. In those cases, you run hard or you Alt+F4, but having 700-800 ES regen per second can really buffer any additional damage, which might save you.

DisAdvs:
- ZO doesn't offer instant life leech like VP does. CI builds commonly get VP to prevent one-shotting themselves on reflect mobs. ZO isn't as effective here, but with a quality life leech gem, high armour, and 700-800 ES regen per second, you'll mitigate reflect damage significantly. Since this build is melee, you'll also be in sight of any reflect auras, so you should be able to pop a Granite flask before engaging the enemy. You can also opt to cast Enduring Cry + Immortal Call for a brief period of immunity to physical damage, which I have done in this build (you can get 3.6 seconds with a non-quality lvl 20 Immortal Call and 3 Endurance charges).

This is for lvl 90.

The passive tree is subject to changes, but probably not by much.

Here's one of the possibilities.

Normal: Kill all for 1 skill point.
Cruel: Help Oak for 18% increased physical damage.
Merciless: Help Kraitlyn for 1 Frenzy charge.

There are some uniques you want.

Marohi Erqi http://pathofexile.gamepedia.com/Marohi_Erqi
The Blood Dance http://pathofexile.gamepedia.com/The_Blood_Dance
Dream Fragments http://pathofexile.gamepedia.com/Dream_Fragments (either this or Auxium)
Shavronne's Revelation http://pathofexile.gamepedia.com/Shavronne%27s_Revelation (only use if you have 1272+ mana with non-quality Mana Leech or 1529+ mana with 20% quality Mana Leech)
Atziri's Foible http://pathofexile.gamepedia.com/Atziri%27s_Foible (optional but recommended, but don't use with Shavronne's Revelation)
Auxium http://pathofexile.gamepedia.com/Auxium (either this or Dream Fragments)

The rest should be ES gear: chest, helmet, gloves, and jewelry.

6L (7L with Marohi Erqi):
Frenzy - Melee Physical Damage, Melee Damage on Full Life, Melee Splash, Added Fire Damage, Mana Leech, (Increased Area of Effect)
* Replace Added Fire Damage with Life Leech for reflect maps.

The rest (at least what I might do):
Leap Slam - Faster Attacks; Blood Rage; Decoy Totem
Enduring Cry, Enduring Cry, Enfeeble, Vulnerability
Immortal Call, Molten Shell, Temporal Chains - Increased Duration
Purity, Determination, Grace, Discipline, Vitality/Hatred (optional) - Reduced Mana
* I grouped these to fit in a 6L chest and the other gear.

Starting off as witch for this build, as with most CI builds, is most efficient. You can level however you want, but I think using Freezing Pulse or Discharge are good ideas. You can even change to dual Spark totem and do low-life farming, since the pathing around the passive tree is almost the same.

Just spec out of crit and life nodes (though if you're low-life farming you won't have many life nodes), then respec into ES and Frenzy charge nodes (and some other nodes like Resolute Technique). It's a weird build transition, I know, but it'll work.

(One thing I forgot about is that the bandit rewards are different. Having 1 less Power charge and 4% less cast speed shouldn't matter that much, but you can decide to level as Ele Cleave or something if you prefer.)

The alternative to using Marohi Erqi or another 2H weapon is using Soul Taker + ES shield. With Soul Taker, you'll be doing less physical damage, but you'll be able to run more auras and use Shavronne's Revelation, which bumps you to 15.07% ES regen, or around 1.2k ES regen per second with 8k ES. I've also been toying with the idea of getting high shield block chance and Aegis Aurora.

But honestly if I were to do this alternative, I'd wear Fairgraves' Tricorne and a high ES shield instead of using a high ES helmet. Being shock immune is AMAZING.

Why Frenzy?
You can use something else if you want, but I felt that if I am going to use Frenzy charges for the ES regen, I might as well use a skill that keeps up 7 charges most of the time (or at least can generate them quickly). Using 20% quality lvl 20 Frenzy while having 7 Frenzy charges gives 84% increased physical damage and 105% increased attack speed (I already accounted for the deduction from Blood Dance). With Melee Physical Damage and Melee Damage on Full Life, you get two damage multipliers.


Why Marohi Erqi?
You're right, it's slow. However, it has insane damage per hit and using Frenzy will get you to more than 2 attacks per second without Multistrike or Faster Attacks (it's about 2.261 APS with 7 Frenzy charges and lvl 20 Blood Rage with Inner Force). The lvl 15 Increased Area of Effect also helps increase the Melee Splash radius.

Single Target Damage Calculation:
Assuming...
20% quality 225% Marohi Erqi
165 Str (33% increased physical damage)
52% increased physical damage with maces on the passive tree
10-20 added physical damage from other gear (gloves, amulet, rings)
20% quality lvl 20 Frenzy (84% increased physical damage with 7 Frenzy charges)
10% quality lvl 20 Melee Physical Damage (5% increased physical damage, 49% more damage)
10% quality lvl 20 Melee Damage on Full Life (5% increased physical damage, 49% more damage)
Non-quality lvl 20 Added Fire Damage (39% of physical damage added as fire)
Lvl 20 Melee Splash (57% increased physical damage, 16% less damage to main target))
Lvl 20 Hatred (25% of physical damage added as cold)
2.261 APS (7 Frenzy charges and lvl 20 Blood Rage)
Inner Force
Enemy has 0 armour and 0% fire/cold resists

Minimum - (92+10+10)*(1+2.25+0.20)*(1+0.33+0.52+0.84+0.05+0.05+0.57)*1.49*1.49*0.84*(1+0.39+25)*2.261 = 8978 DPS
Maximum - (138+20+20)*(1+2.25+0.20)*(1+0.33+0.52+0.84+0.05+0.05+0.57)*1.49*1.49*0.84*(1+0.39+25)*2.261 = 14268 DPS
Average - 11623 DPS
(Keep in mind that this is a single target.)

Why you so weird bro?
