The idea of this build is that you focus all your effort/damage on getting from one elite pack to another as quickly as possible to maintain your In-Geom (which is where your damage goes from "average" without In-Geom to "6x super damage" due to the cooldown reduction on explosive blast) - setting trash pack size to anything but max will limit this build, as does changing the Elite Range and the Ignore Trash Range, as does setting monster values in Grifts. If you have vaguely decent gear, using these settings, and have an In-Geom, 6 piece Tal Rash, 4 piece Firebirds and the Wand of Woh (and Paragon 500+) you will finish Rifts in 3-4 mins and G-Rifts 58-60 in 3-4 mins (you can go to about G-Rift 65 or so with these builds, but then you die too often trying to kill the first elite pack to make it viable - stick at 58-60 and push G-Rifts with the DMO Wiz build). All of the following builds work fine - (it adds 30 seconds to the Rift time if you are using the Sages Set).
You are tanky - so turn down all avoidance cept molten core (which you will die to no matter what).
Max range for elites.
Use Teleport OOC
Use Teleport at 100% health.
You don't need to avoid minions.
Don't attempt to avoid AOE - you can handle it!
Turn off: Gold Pickup, Opening Chests, Opening Weapon Racks, Examining Bodies. Turn Off picking up yellows and blues, whites as well unless you really need them (don't forget a white is worth 9x the mats of a yellow - so forget picking up yellows ever).
***NOTE*** My one recommendation is to change whatever the build suggests as a Primary Attack (Signature Spell) to instead be Spectral Blades of the same elemental type - this ensures the bot gets up close and personal to all mobs and Explosive Blast in their faces, if you are using a ranged Primary the Explosive Blast often ends up out of range. The other REQUIREMENT of all of these builds is that you have Nemesis Bracers equipped or in cube.
***G-RIFT NOTE*** If your In-Geom buff is gone/off for more than 7-8 seconds between Elite packs then turn down your G-level for increased efficiency/exp.
Yes it will leave a few Rift Globes behind - it moves out of range of them too quickly, but you get more exp or more DB's and still finish in under 5 minutes.
