Passive Skills


As a Delsere's Magnum Opus set build, you have to constantly keep in mind your dependence on dropping Slow Time Slow Times that regularly envelop your priority targets. Some leeway was given with later reworks to DMO (you do not need to be in the Slow Time Slow Time radius to gain damage reduction, and affected enemies are more susceptible to damage for 5 whole seconds after exiting the bubble), but with the built-in resets coming from your generator attack and Explosive Blast Explosive Blast, you should make a point to regularly apply Slow Time Slow Times as well. Spam Explosive Blast Explosive Blast on cooldown to maintain the bonuses of Orb of Infinite Depth Orb of Infinite Depth and keep the Storm Armor Storm Armor shield active at all times. Last but not least, reposition smartly with Teleport Teleport.


Skills and Runes

The main damage dealer and namesake of the build is Arcane Orb Arcane Orb Frozen Orb Frozen Orb — a long range projectile attack that hurls a pulsating orb of frost, exploding at the end of its 40 yard travel distance. Do your best to internalize the length of the Frozen Orb Frozen Orb shot to maximize the benefits of said detonation, as it is stronger than the piercing projectile while it is moving. Make a point to always cast Arcane Orb Arcane Orb after you fully stack Triumvirate Triumvirate, especially if the Cold cycle of Convention of Elements Convention of Elements is coming up.

To counteract the considerable Arcane Power spending of Frozen Orb Frozen Orb — 30 AP per shot — you will be including a primary attack in the build, adding a resource generation angle to it through Arcane Power on Crit on gear (see this build's gear page for more information). You have a good number of viable primary attacks for the slot, including the protective Spectral Blade Spectral Blade Barrier Blades Barrier Blades, the crowd control synergy of Magic Missile Magic Missile Glacial Spike Glacial Spike, or the general recommendation, the superior proc coefficient of Shock Pulse Shock Pulse Piercing Orb Piercing Orb.

Slow Time Slow Time is integral to DMO setups, amplifying the damage of multiple skills against affected enemies, as well as cutting incoming damage by 60%. You should bolster its damage amplification angle by selecting the attack speed buff of the Stretch Time Stretch Time rune.

Despite its set-induced damage bonuses, Explosive Blast Explosive Blast will be included in the setup mostly as means of protection and buffing your other damage dealing skills. You will be taking the multiple explosions of the Chain Reaction Chain Reaction rune, quickly maximizing the buffs from the Orb of Infinite Depth Orb of Infinite Depth source. Note the constant tug of war between the buffs coming from the melee range Explosive Blast Explosive Blasts, and far ranged Frozen Orb Frozen Orb that thrives off distance; to balance between them, strive to always place yourself near less threatening enemies to maintain the Orb of Infinite Depth Orb of Infinite Depth buffs, while keeping dangerous, priority targets like elites to gain the most out of Frozen Orb Frozen Orb.

When pushing Greater Rifts, immediate repositioning will often be required — whether it's evading a bad affix or engaging fresh enemies. Early on in character progression, this slot can be temporarily taken by Teleport Teleport with the damage reduction of the Safe Passage Safe Passage rune — a beginner-friendly choice. Later on, you will focus on microing your character's position and exerting stronger control over the enemy — this is done with Black Hole Black Hole, also sporting a damage increase and reduction buff with the rune Spellsteal Spellsteal.

Rounding skills out, you will be adding Storm Armor Storm Armor to the build. With a fire-and-forget duration of 10 minutes and a negligible damage proc, it can be easily overlooked if not for the potent flat resource cost reduction of the Power of the Storm Power of the Storm rune and the massive damage reduction properties of the cubed Halo of Karini Halo of Karini.

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



Two defensive staples provide the foundation of your passive selection. Reworked into a comparable function to other cheat deaths, Unstable Anomaly Unstable Anomaly gives you one shot at dodging a lethal situation. Operating on a standard 60-second cooldown and adding a 3-second stun to nearby enemies — plus a solid 400% max life shield for 5 seconds — it will become a constant companion to your Greater Rift pushes. To shield you prior to the cheat death proc, Unwavering Will Unwavering Will will complement your semi-static fighting style and adds significant Toughness with the 20% Armor and All Resistance buff.

The observant reader will notice that with the inclusion of Arcane Orb Arcane Orb Frozen Orb Frozen Orb, Shock Pulse Shock Pulse Piercing Orb Piercing Orb, Black Hole Black Hole Spellsteal Spellsteal and Explosive Blast Explosive Blast Chain Reaction Chain Reaction, we have added all four elements available to Wizards — so you can make maximum benefit of the additive Elemental Exposure Elemental Exposure damage buff.

Finally, take Power Hungry Power Hungry — it is the mirror of Audacity Audacity, reworked into a multiplicative damage increase against enemies further than 30 yards. This passive synergizes excellently with the long range orientation of the build, coming from both Frozen Orb Frozen Orb and Zei's Stone of Vengeance Zei's Stone of Vengeance.
