I always had trouble DB Farming with Wizard in T16.
I guess the Vyr build with Messerchmidt Reaver can do it now, so I am probably late to the party…
But anyway here is an alternative, an easy T16 Wizard build, with sage set and Aether Walker using the DMO set (so a tad slow, I will agree, you have to put down those slow time bubble).
Strategy and build:
The build has both cool down reduction and cost reduction and arcane power on crit… Because the goal is to spam 3 expensive skills: slow time, arcane orb and teleport. (prodigy might be superfluous, arcane on crit does wonder)
other than that, teleport around, make a bubble, fire shock pulse a few time (for the Trimuvirate bonus), then hold arcane orb, bob is your uncle!
I am using Ancient Parthan Defender instead of Nemesis because I had toughness issue, but with Slow Time Exhaustion and Parthan Defender it’s cake walk.
Arcane Orb need be Obliteration for the explosion (Unstable Specter) damage bonus
