Build Guide


The purpose of this build is to farm Greater Rifts between 90-100 in times ranging from 1:30-3:30.

If the build feels like you are farming Torment XIII without Ingeom then u found the right tier.

Note: This build only works with this http://www.diablofans.com/builds/94504-ze-necromancer-support-rathma-speed Support Necromancer due to his insane globe spawning.


As you can see above there is only one flexible slot which is the Offhand. In fact it doesn't matter what you use there just make sure it has the best possible stats. Dayntee's Binding can also be switched out with The Withing Hour is you feel comfortable with your toughness. Same goes for Decrepify that can be switched out with Devour which has multiple useful runes. Or keep the Decrepify for the increased cooldown and dmg reduction even while wearing The Witching Hour.

[Stat Priorities]

General rule of thump CHC>CHD>CDR>IAS, this doesn't apply to your amulet here you obviously want Elem. DMG, CHC, CHD.

Also you want Maximum Essence and Skeletal Mage Damage % on all the pieces possible.

[Skeletal Mages & Max Essence]

In this section I will go over the Skeletal Mage Skill and their Mechanics as well as Max Essence since it is the sources of your Damage.

Skeletal Mages attackspeed does NOT benefit from your Sheet APS, only Tasker and Theo work on it and brings the attack animation from 30 frames down to 20( 3 instead of 2 attacks per second). However that doesn't mean they don't benefit from your APS. Your Sheet APS is just simply a multiplier in the damage calculation.

Singularity Mages attack for 200% Weapon Damage. From the Rune you will get a multiplicative bonus which calculates like this

3%* (Current Essence-(40*(1-RCR%))+1.

So with Max Essence( excluding SoJ) while casting and RCR only from paragons the Mages will hit for 3944% Weapon Damage with Simulacrum and 1964% without.

This Formula shows you how RCR works on the Singularity cast however don't get tricked in to thinking RCR is a valuable stat. For example gaining an additonal 8% on shoulders would be a Damage increase of 0,438%.

Missing out on a Maximum Essence Roll with Simulacrum active is a Damage loss of 11,7% or 10,6% without it due to the combined effect of Reilena's Shadowhook and the Singularity Rune.

Missing out on 2 Maximum Essence on for example your Offhand is only a Damage loss of 1,1% or 0,1%

So for instance if you have a new ancient Offhand that says 8% Damage increase in game, but other than your non ancient one it doesn't have Maximum Essence it is not an upgrade for your Damage

The Gameplay is actually really simple so I will just point out a few things here.

- casting Simulacrum with a gap of 2 seconds or lower to the physical rotation will give you 3 rotations however that wont always be the right decision

- cast Mages with Full Essence

- have Bone Armor active

- keep decrepify up

- surviving > Oculus

- if you are playing the necro with frailty don't forget the curse!
