Ancestral and Mythic Uniques

See below for information on useful Uniques and how to integrate them into this build:

Deathless Visage [Required]

This is the build defining item for any variant of Bone Spear. Echoes produced by Deathless Visage deal significantly more damage than Bone Spear itself. Echoes and secondary projectiles from “Chance for Bone Spear Projectiles to Cast Twice” each able to trigger Lucky Hit with a high chance. As a result every single Bone Spear cast can trigger Lucky Hit multiple times. Additionaly, there is a massive amount of skill ranks to Bone Spear as a bonus.

Obtained from Varshan Lair Boss.

Indira’s Memory [Required]

Required piece for the build for converting Bone Spear into Blood skill. High amount of ranks to Tides of Blood make it worthwhile to use Overpower.

Obtained from Beast in the Ice Lair Boss.

Path of Trag’Oul [Recommended]

These Unique boots are used to expand Bone Prison size and reduce its cooldown for faster Bone Spear setup. Bone Prison on demand is required for Bone Duster’s Aspect synergy. Losing Aspect of the Cursed Aura will require Sanctified alternative or Igni Wat runeword.

Obtained from Grigoire Lair Boss.

Shroud of False Death [Best in Slot]

Best in slot Mythic Unique Chest for most Necromancer builds. It provides significant effective damage multiplier and utility improvements all across the board, via +1 All Passives bonus. Sizeable All Stats affix makes Rare Paragon Node bonus requirements easier to fulfill. Straightforward Chest slot replacement.

• Inspiration

For the reinforcement, stick with Aldkin, utilizing his Flame Surge to trigger Abhorrent Decrepify when any Ability is being cast.

• Flame Surge

Rotation and Build Mechanics

This is build is designed to isolate enemy packs in Bone Prison and destroy them with shattering Overpowering Bone Spears.

Rotation and Playstyle

1. Approach the pack to trigger Igni Wat runeword when Soulrift is used.
2. If no Corpse available: create a Corpse with Reap, pull pack together with Blighted Corpse Tendrils and lock it in with Bone Prison
3. Spam Bone Spear into Bone Prison.
4. Inbetween keep re-casting Reap, Blighted Corpse Tendrils and collecting Blood Orbs to force Rathma’s Vigor for Overpowers.

Which Elixirs Should You Use?

Visit the Alchemist and craft an Elixir providing any Resistance you need most, Elixir of Precision II, if you lack Critical Strike Chance, or the Elixir of Fortitude II to increase overall Toughness. Recommended incenses are Reddamine Buzz, Soothing Spices, Sage’s Whisper. Make sure to keep your Health Potion upgraded!
