Level 91 Detonate Dead Elementalist^3.22

Notes

--------------Build Rating------------

Boss Damage: 8/10
Damage Uptime: 10/10
Clear speed: 7/10
Defense: 5/10

---------------IMPORTANT SPECTRE INFORMATION---------------

The build works by casting Desecrate and Detonating the corpses that you spawn. To deal single target damage you need to detonate high life corpses which can be spawned using Desecrate with high life spectres 
summoned.

To maximize single target we have an infinite ignite using defiled forces if you keep cursing the enemy.

As of 3.17 you only need to raise 1 spectre, the highest life one possible, then you can unequip Raise Spectre.  The raised spectre remains in your Desecrate corpse pool 
even after it dies and without Raise Spectre equipped.

---------------Leveling---------------

Level with Rolling Magna + Holy Flame Totem until Arma brand + Cremation
OR you can level with Orb of Storms + Stormblast Mine, whatever you prefer

Make sure you level Desecrate as you level, your DD damage directly scales with the level of desecrate

You can level as DD as Elementalist if you want.

---------------Extra tips---------------

Get these two Unveil mods on helm and chest:

- Chest:  "6% of Physical Damage from Hits taken as Fire / Lightning Damage" (Gravicius unveil).  Important for phys reduction!
- Helmet: Phys taken as fire (Korell unveil)

Swap Grace out for Purity of Ice/Fire/Lightning on bosses

---------------Gear---------------

All of your armour is basically just rares + life + spell suppression which can be crafted with essences until you get a good life roll and spell supression

Weapon is crafted with spamming fire harvest, pretty annoying to hit a really good sceptre

--------------Skill Rotation--------------

Curse -> Desecrate -> Detonate dead -> Flame Surge -> Keep cursing to reapply ignite -> Flame Surge to keep burning ground up

--------------Spectre Info--------------

Raise Spectre's most recent monster types are now saved to your character and may be Desecrated. The size of this list is capped by your Spectre limit.
Desecrate and Corpse Walk now have a static 15% chance to spawn a Spectre Corpse, rather than a 2x relative weighting compared to all other possible corpse types.
Spectre versions of monsters that have very high life total are now brought down to match Kitava's Herald monster HP %.

TL;DR:
Get an Auric Colossus or Auric Champion from Act 3 Solaris Temple Level 2 or kitava's herald from Cathedral Roof Top Act 5 or 10
You can throw away your Spectre gem after you summon one.
 
Explanation:
All Spectres should be capped at 360% Life, meaning you can get any monster that is 360% Life or above. (Same as Kitava's Herald)
You only need one, desecrate has a static chance to spawn Spectre corpses.
The monster type will get saved to your character, your desecrate pool will not lose it even if you unequip the gem.
