Decompose, Blight, Sever, and Reap are on our skill bar for Reaper's Pursuit value. You do not need to press them in this build as this is a 1 button build.

A roll of Ranks to Core Skills in the gloves are used to equip Blight and Sever without using Skill Points on them.

Alternatively the Skeletal Warriors Defenders Sacrifice can be used for a great boost in your resistances if staying alive is more important than damage.

There are very specific breakpoints for this build to work. Each one will be covered in-depth in the How It Works section. So make sure you read it because the build might struggle to work otherwise.

The two main breakpoints are as follows, which are covered in more detail in the How It Works section:

  1. To get Bone Spirit to a zero second cooldown with Rapid Ossification to spam it
  2. To reduce the cooldown of our Aspect of Metamorphosis Evade in combination with the Evade Cooldown Reduction tempers and Attacks Reduce Evades Cooldown implicit on our Boots to permanently reset our Dash cooldown for insane mobility. This Boot implicit is the core to making this build work so make sure you have it.

Your priority for Bloodied Affixes are as follows:

  1. 3% Core Stats per Skill Streak tier
  2. Every 25 kills, gain Berserking
  3. Cooldown Reduction per Kill Streak tier
  4. Movement Speed per Kill Streak tier
  5. Increased Experience per Killstreak tier

How it Plays

  1. Cast Bone Storm for the Critical Strike Chance, Attack Speed, and Damage Reduction
  2. Use your Aspect of Metamorphosis Evade to close the distance
  3. Cast Bone Spirit to kill the enemies and reset your Evade cooldown
  4. Dash to the next enemies with Aspect of Metamorphosis to stack Jah
  5. Jah teleport as needed for mobility
  6. Repeat.

How it Works

How The Mobility Works

The mobility is the core of the build, so its most important you understand how it works. The build utilizes the overlooked mechanic that Cooldown Reduction impacts your Evade cooldown, which is especially important with Aspect of Metamorphosis.

With that in mind, its imperative that you have the Attacks Reduce Evade Cooldown intrinsic on your boots. The goal of the build is to be able to cast one Bone Spirit and instantly reset your Evade cooldown.

When you get the right amount of Cooldown Reduction, your Evade becomes an incredible Offering generator with the Cem Rune. We combo this with the Jah Rune for even more insane mobility.

Requirement Breakpoints

Each breakpoint will be listed and explained in detail below, but here is a quick and easy checklist of the breakpoints:

  1. One Greater Affix maximum resource roll, or two regular rolls.
  2. Two Greater Affix Tempered Macabre Skills Grant Essence tempers on both your rings
  3. A Greater Affix Rapid Ossification temper on your Amulet
  4. Have an Elixir of Resourcefulness active for the increased Max Essence
  5. Either a Greater Affix roll of Resource Generation on Shroud of False Death, or 660 Willpower through the Paragon if its not Greater Affix to generate 200 Essence a cast (or Yen's Blessing)
  6. A Greater Affix Evade Cooldown Reduction temper on your Boots
  7. Masterwork hits on the Macabre Grants Essence temper and Evade Cooldown Reduction Temper
  8. 5 Cooldown Reduction rolls in your gear, with 3 or more of those 5 being Greater Affix for the best results to hit 55% Cooldown Reduction on your character stat sheet.

    As an important reminder, Cooldown Reduction suffers from diminishing returns. So while there is a Cooldown Reduction cap of 75%, you need a lot more than 75% Cooldown Reduction in your gear to hit the cap.

Evade Cooldown Reduction

The goal of this breakpoint is to get the cooldown of our Aspect of Metamorphosis to match the 1.9 second reduction we get from our Attack Reduce Evade Cooldown implicit from our boots.

To do this, a Greater Affix Evade Cooldown Reduction temper roll is needed on the boots alongside 5 Cooldown Reduction rolls in your gear, with optionally 3 or more of those 5 being Greater Affix for the best results.

It is important to remember that Cooldown Reduction effects your Evade cooldown.

Infinite Bone Spirit Cooldown

To be able to spam Bone Spirit without a cooldown and without relying on them to hit an enemy, Rapid Ossification is used heavily for the flat cooldown refunded by spending Essence.

To do this, a Greater Affix of Rapid Ossification temper roll is needed on your Amulet alongside 2 Masterworked Greater Affix Macabre Grants Essence tempers on your rings.

The reason we need so much Essence generation to reduce the cooldown of Bone Spirit to zero is because of Rapid Ossification. When using an Elixir of Resourcefulness and a Maximum Resource roll in either the Focus or Amulet, the build will have over 200 max essence to trigger Rapid Ossification twice per cast for a total reduction of 4.5 seconds.

In order to gain 200 Essence a cast, not only are the Greater Affix Macabre Grants Essence tempers needed with a Masterwork hit needed, but a Shroud of False Death or Yen's Blessing (if doing Hordes. A detailed breakdown will be found under the Uniques section) with a Greater Affix in Essence Generation is needed. If players lack the Greater Affix Resource Generation in their Shroud of False Death then 660 or more Willpower is needed to generate 200 Essence a cast.

This breakpoint only matters for AFK Infernal Hordes. If players are only looking to speed farm Pits and Nightmare Dungeons then Enhanced Bone Spirit can refund 7 seconds of cooldown, making up for the lacking breakpoint.

Essence Generation

Macabre Grants Essence tempers are fantastic with Bone Spirit as the Essence is first consumed to deal massive damage, and then the tempers trigger to give you all your essence back because Bone Spirit is a macabre skill. Getting these tempers as high as you can is core to your essence management.

Uniques


Blood Moon Breeches: Massive Crit damage multiplier. The crit chance also helps reach 100% crit chance.

Crown of Lucion: This gives one of the highest damage bonuses we can get, and without any of the downsides as we're already spending all our essence. It even has cooldown reduction on it!

Yen's Blessing: This unique will be used for AFK farming hordes until Shroud of False Death thanks to the 27% Resource Generation you can get with a Greater Affix and a Masterwork hit. You will lose the ability to reset your Evade cooldown, but its worth it to be able to AFK comfortable in Hordes.

Path of Trag'Oul: While we can't run it on the Speed Farming variants, we can however make perfect use of them on the Boss Killing variant thanks to the massive amounts of Maximum Essence that passive provides.

Shroud of False Death: The most vital piece of gear in the build. It allows you to hit all your breakpoints with more points in things like Rapid Ossification as well as a bonus to all your damage modifiers like Gloom and Evulsion. This unique is a must have for any end game variant.
