A caster whose focus is Vitality damage, with a secondary focus on Aether damage. This is more of a battle mage than a fully fledged caster class, but it still has a heavy focus on Vitality damage. This build uses fewer abilities overall, but the few abilities it does use are pushed to their full potential, making them very potent when activated. This build relies fairly heavily on luck when finding or farming specific Rare items with the correct prefixes. These can be replaced with any Legendary pieces of gear that offer similar stats. Reassign augments and components to compensate for any resistances that may be lacking.
Bone Harvest, the first skill of this build, which on its own does not offer significant advantages, but its final ability, Soul Harvest, further enhances our Vitality damage, which is why it is chosen. Only a few skills in the Necromancer tree are selected, as the goal is to maximize the effectiveness of the chosen skills from both trees. Siphon Souls and Harbinger of Souls both further increase our Vitality damage. Curse of Frailty, paired with Vulnerability, leaves enemies weakened against the Vitality damage we deal. Solael’s Witchfire provides a constant increase to all damage, while Doom Bolt delivers massive burst damage. You also have the option to reallocate points from the Summon Hellhound tree to other skills as you see fit for your preferred playstyle.
This will be your starting class, with a primary focus on progressing the Mastery Bar. There are not many early skills worth investing in within this tree, but we begin here to unlock Bone Harvest as our right mouse button ability and to start advancing the Mastery Bar. The goal is to reach the later skills, specifically Siphon Souls and Harbinger of Souls.
Because there are only a handful of valuable skills in this tree, we focus on fully maxing them out to maximize our Vitality damage.
This will be your secondary class, with an early focus on the Solael’s Witchfire tree to increase Vitality damage. Gradually progress the Mastery Bar to unlock later skills. Curse of Frailty becomes essential in higher difficulties, as its debuff weakens enemies and allows your attacks to deal significantly more damage.
