As a Delsere's Magnum Opus set build, you have to constantly keep in mind your dependence on dropping 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 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 manual casts of Energy Twister, you should make a point to regularly apply Slow Times across the battlefield. Your DPS mechanic comes from the interplay between channeling Arcane Torrent (which casts Energy Twisters via the worn Etched Sigil) and their merging and damage improvement via the rune Raging Storm (granted by the sword). During the actual fight, you are able to simply hold down Arcane Torrent and receive the stacked casts of Energy Twister through the Etched Sigil proc. Also — while they are passive buffs, make a point to watch the uptime of Magic Weapon and Storm Armor, reapplying them as necessary and displacing enemies with Black Hole.

Your primary damage dealer is found in Energy Twister, a former group favorite that, while under the radar of many, retains most of its monstrous AoE DPS properties. You will be getting the rune with the most damage potential, Raging Storm, for free from the updated The Twisted Sword powers — empowering and enhancing the number of twisters that are able to collide and converge. To ensure you won't need to focus on manual collision of Energy Twisters, you will take the rune Wicked Wind and leave the Arcane Torrent- Etched Sigil combo to produce them automatically.

As mentioned above, you will need to take Arcane Torrent, as its channeling mechanic interacts directly with the free Energy Twister spam of Etched Sigil. Rune-wise, take the damage reduction of Flame Ward, as damage output will not be the focus of this skill slot — simply the automated production of your main damage dealer, Energy Twister.

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 can either bolster its damage reduction angle by selecting the Exhaustion rune (safer), or its damage boosting via Time Warp (our default recommendation).

There is some rune-alternating freedom in your utility slot as well; Magic Weapon offers an attractive, long-lasting damage buff by default, and you can either add a defensive property to it from the rune Deflection, or alleviate your near-constant resource starvation with the rune Conduit. Both options are perceived as viable, so tailor the ability to your particular needs.

Black Hole is an excellent utility inclusion for several reasons. First, it brings a monster grouping skill to the setup, which is always welcome before you start your channeling barrage; second, it packs a utility combo of reducing enemy damage and increasing your own via the rune Spellsteal; and third, it acts as a proc for the Arcane portion of the Elemental Exposure buff.

Rounding skills out, you will be adding 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 massive damage reduction properties of Halo of Karini (see this build's gear page for more information). You will be taking the rune Shocking Aspect for the superior uptime of the procs for the Karini buff. Alternatively, you can consider Scramble for the additional movement speed, or Power of the Storm for the Resource Cost Reduction.

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. Blur offers a simple, straightforward, but very effective survival bonus — percentage-based damage reduction. Further strengthening your shield, Unwavering Will will complement your semi-static fighting style and add significant Toughness with the 20% Armor and All Resistance buff.

Elemental Exposure is taken to bolster your damage through your myriad of elemental damage sources. Notice that the passive bumps damage in 5% increments per element used; you fulfill the fire with Flame Ward, lightning with Storm Armor, arcane with Spellsteal. The final bump will come from the damage type of your weapon, The Twisted Sword — a lucky roll (or reroll) of the base damage from another type (i.e. physical or arcane) into cold will bring the last piece of the damage buff.

Finally, take Power Hungry — it is the mirror of 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 and Zei's Stone of Vengeance.
