Passive Skills


When doing farming content, the Blood Mage Necromancer begins runs by scouting out the area with a few quick Blood Rush Blood Rushes, ideally finding a large pack of enemies to fight. Proceed to activate Bone Armor Bone Armor with a good number of surrounding foes to get as many stacks as you can; follow it up with by sicking your melee minions with Command Skeletons Command Skeletons to trigger the Jesseth Arms bonus, and starting the main course — summoning Skeletal Mage Skeletal Mages to begin the devastation. Strive to stay at or near the cap of 10 Skeletal Mage Skeletal Mage summons at all times. In this generator-less setup, you will regain Essence by spamming Devour Devour at all times, and activating Land of the Dead Land of the Dead as often as the resets from In-geom In-geom will allow.


Skills and Runes

The primary damage dealer of the build are the Skeletal Mage Skeletal Mages; a hard-hitting Necromancer spender, sitting at a costly 40 Essence base. In order to trigger the Trag'Oul set bonuses, you will have to pick the blood-spending Life Support Life Support rune by necessity. In turn, this restriction will reward you with 2 extra seconds duration — a handy, forgiving bonus for both the frantic pace of farming and the demanding Greater Rift progression.

To supplement the damage of the Skeletal Mage Skeletal Mages, you will have a secondary summon at your side — Command Skeletons Command Skeletons. However they will not be focused on as a source of damage, as their role will be restricted to a proc of the Jesseth set (Jesseth Skullscythe Jesseth Skullscythe and Jesseth Skullshield Jesseth Skullshield). In order to fulfill the set condition, you should not forget to set them on a target every fresh fight. You will add some crowd control to the skill via the Freezing Grasp Freezing Grasp rune, which also provides you with regular procs of Krysbin's Sentence Krysbin's Sentence — do not forget to apply the freeze multiple times on prolonged fights.

The next two skills in your arsenal will offer utility and mobility. In a farming setup without a generator, you will rely on the fast kill speed of regular Rifts plus your Corpse consumption mechanic, Devour Devour, to restore your Essence. You will also add a considerable health sustain aspect to the skill with the rune Cannibalize Cannibalize . Note the lack of casting animation to Devour Devour, and spam it freely. In a Trag'Oul rifting setup, you will also do well to add Blood Rush Blood Rush; the 2-piece set bonus nets you all the runes, most notably the cost removal of Hemostasis Hemostasis and the double charges of Metabolism Metabolism for maximum farming convenience. In case you ever run out of resources (unlikely, but possible in an unlucky combination of Land of the Dead Land of the Dead downtime and lack of nearby Corpses), remember that Molting Molting will spawn you a free Corpse to Devour Devour and kickstart your damage with.

The final two active skills will be devoted to utility and crowd control. On a convenient 10 second cooldown, Bone Armor Bone Armor will provide a decent 30% damage reduction at the maximum 10 stacks, as well as a vital 2-second stun from the Dislocation Dislocation rune. During speed farming, the powers of In-geom In-geom (cutting 10 seconds flat off cooldowns while active) will practically ensure an on-demand stun for every fight, and a guaranteed proc of Krysbin's Sentence Krysbin's Sentence. Finally, Land of the Dead Land of the Dead Frozen Lands Frozen Lands will consistently freeze entire screens worth of enemies while it is up, indirectly ensuring your survival and providing an all-around Krysbin's Sentence Krysbin's Sentence proc. Its massive cooldown will be offset by regular elite kills and In-geom In-geom's power, so activate it as many times as you can during a run (see this build's gear page for more information).

This concludes the overview of the Active Skills, now let us look through the Passives.



Since this is a Skeletal Mage Skeletal Mage-centric build, everything that augments or extends their power is priority; thus Extended Servitude Extended Servitude takes a firm slot in your passive selection for the Mage duration increase.

Blood for Blood Blood for Blood is a great addition to a Trag'Oul setup, even more so during farming. Due to the health globe pickup radius synergy with Avarice Band Avarice Band, you will consistently have this passive stocked up with a few charges — enabling carefree spam of Skeletal Mage Skeletal Mages as a result.

Blood is Power Blood is Power is the Necromancer's take on passives such as Evocation Evocation and Beacon of Ytar Beacon of Ytar — along with the significant drawback of needing to lose your health reserve equivalent to trigger it. Since it counts off pre-mitigation values and with the natural flow of Trag'Oul set gameplay (spending health alongside Essence), you have a guaranteed trigger of its effect every time you put Land of the Dead Land of the Dead on cooldown.

You have some freedom of choice in your last passive slot. The general recommendation is Dark Reaping Dark Reaping, a speed farm-oriented passive that replenishes both health and Essence as you dominate your enemies in easier content. You naturally fulfill its requirements by wielding Jesseth Skullscythe Jesseth Skullscythe. Alternatively, you can fall back to the safety of Final Service Final Service to ensure a random drop of the Goldwrap Goldwrap bonuses will not result in your untimely death. Ideally, you will not have to choose between those passives with a nicely rolled Hellfire Amulet of Intelligence Hellfire Amulet of Intelligence.
