Speed Farm Bone Spirit

Bone Spirit remains to be one of our best speed farming builds thanks to Decaying Humerus that allows it to leverage the insane damage multipliers Shadow Builds have for incredible damage in combination with the Jah Runeword and Metamorphosis for incredible speeds.

1) Cast SoulRift
2) Cast Decrepify
3) Giga Blast with Bone Spirits
4) Jah teleport and Metamorphosis to the next enemy pack and repeat

Banished Lords Talisman is no longer best in slot thanks to the nerfs to Overpower. Instead we dip into the Shadow Multipliers given to us by Aspect of Decaying Humerus

Essence in the build is generated by both the Macabre Grants Essence tempers which gives us a ton of essence every time we cast Bone Spirit

Lucky Hit Chance to Grant Essence is incredibly strong in this build for Pits as the Imprisoned Spirit aspect not only doubles our number of Bone Spirits, but that extra Bone Spirit will also then trigger another set of Phasing Poltergeist's Aspect hits. In all it allows us to hit 8 times per target with a single cast of bone spirit, allowing us to constantly trigger our Lucky Hit Chance effects such as Lucky Hit Chance Essence and Necrotic Fortitude for Barrier

Requirements

This build has some requirements to come fully online, and they are important to reach but not too difficult. You need to have 100% Crit Chance while fully buffed. Luckily due to extra crit chance from Bone Storm and Blood Moon Breeches, the crit requirement is fairly easy to hit. You also need 200 maximum essence while fully buffed to max out the Ossified Essence key passive. Keep in mind that your Path of Trag'Oul boots will significantly add to your maximum essence pool.
For either requirement you can use Elixirs to help make them much easier to hit, as well as swapping points in the Book of the Dead for extra crit chance or extra maximum essence.

Bone Spirit Cooldown Reduction - How To Spam Bone Spirit

The goal is to aim to have your Bone Spirit on a low enough cooldown that the combination of Rapid Ossification and your Cooldown Reduction gets your Bone Spirit below the 7 second CD refund on Enhanced Bone Spirit in your skill tree. The breakpoints for doing so are as follows:

Speed Farming - 3 skill tree points into Rapid Ossification + 3 Cooldown Reduction rolls in your gear

End Game Pits: 3 skill tree 3 skill tree points into Rapid Ossification + Shroud of False Death to gain the extra skill tree point into Rapid Ossification + 1 Bone Spirit Cooldown Reduction temper with a roll of 14% or higher with 2 masterwork hits

Max Essence

Your target Maximum Essence is 200. You have 100 bases, and many sources throughout the build to increase it. For starters, you can roll it on your Focus, Amulet, and Helmet. You also get 22 Maximum Essence from the Bone Graft board and 16 from Bone Graft itself. You can also get 25 Maximum Essence from the Elixir of Resourcefulness. You also get 20 Maximum Essence from Shadow Mage Sacrifice. Path of Trag'Oul also gives Maximum Essence, up to about 100.
 
You can see that with all these sources of Maximum Essence reaching the 200 requirement is not too difficult.

Essence Generation

All versions of Bone Spirit will use both Lucky Hit Chance Essence as well as Macabre Grants Essence Tempers to generate massive amounts of Essence. Early game you will supplement your essence generation with Shattered Spirit as it helps in all content from NMD to Hordes.

But in end game during Pits, you can opt out of running Shattered Spirit and instead solely rely on Lucky Hit Chance Essence thanks to the higher HP on enemies allowing you to get more lucky hits.
The reason Lucky Hit Chance Essence is so strong on the build comes from the interaction between Poltergeist Aspect and the Imprisoned Spirit Aspect where your Poltergeist Aspect will spawn an additional 3 Bone Spirit Ghosts when Imprisoned Spirit is triggered, leading to a total of 8 difference hits which can all independently lucky hit which allows for insane essence generation against high pit tier content.

Uniques

Path of Trag'Oul: Extra Ranks of Bone Spirit, Maximum Essence, and additional armor just makes these irreplaceable.
Blood Mooon Breeches: Massive Crit damage multiplier. The crit chance also helps reach 100% crit chance.
Shroud of False Death: 1 to all passives as well as a high HP and all stat roll makes this item give way too much tankiness and damage to pass up.
Heir of Perdition: This Mythic Unique gives a 60% damage multiplier as well as extra ranks of Bone Spirit and crit chance. Incredibly powerful.

Mythic Priority Order

Shroud of False Death > Heir of Perdition > Ring of Starless Skies

Horadric Spells

We are using the Astral Pillar as it the best tool for proccing all of our Arcanas. It will instantly shot out waves to execute low health enemies with Bloody Charm. It gives great uptime on unstoppable through Tranquil Stone. Finally, its able to easily proc Fractured Core to remove enemy damage resistance auras.

Elixirs and Incenses

With the abundance of herbs now in the game it is now very easy to grab some consumables to either shore up big weakness with your character or to massively increase your strengths. I highly recommend you regularly keep Elixirs and Incenses running. Below I laid out the best consumables to use for every situation.
 

Elixirs

If you need more of any specific resistance or armor, use those elixirs first. Once your armor capped and resistance capped, look to use the Elixir of Resourcefulness for 25 extra maximum resource. If you're having trouble staying alive and your armor capped and resistance capped, you can use the Elixir of Fortitude to gain a 20% hp multiplier.
 

Incenses

For incense you have a couple of options, depending on what your character needs.

Core Stat

• Sage's Whisper: Generally the best option as it gives the most amount of damage.
• Spiral Morning: Not a bad alternative, as the all stat gives some armor and also helps hit breakpoints in paragon tree. Only use if there's specific paragon nodes you're trying to reach.
   

Resistance

• Soothing Spices: Best all around option as it gives +10% all resistances and +2% max resistance to everything. Only use another option if needed to hit resistance caps.
   

Defensive

• Song of the Mountain: Great early game option for the +300 Armor
• Reddamine Buzz: Gives +750hp, best option if you are already armor capped.

Mercenary

In general Subo gives the most damage via high uptime on Cover Fire. However if you are low on resistances you can pick up Raheir for a smaller amount of damage but lots of all res. For our support we are always using Varyana with Bloodthirst for extra attack speed.

FAQ

Cold Mage vs Shadow Mage Sacrifice

If you can completely refill your Essence on each cast then Shadow Mage Sacrifice is more damage, however if you are not then Cold Mage is better.
