I've tapped out on DBs multiple times this season. Unfortunately I don't have an In Geom Raekor Barb so I tried to think of the next best thing for Wizards who need to farm up those precious DBs.

The nice thing about the gearset is that it overlaps almost entirely with a lot of the current AW builds. For most Wizards, you'll likely only need to craft a Sage's helm and boots and you'll be good to go.

The build's playstyle is identical to the AW/Heatwave T6 speed farming build.

Build

• LMB: Wave of Force/Heat Wave - Fire stack and your primary damage dealer. Teleport into packs and apply directly to the forehead.
• RMB: Arcane Familiar/Arcanot - Necessary for AP regen.
• Skill 1: Teleport/Calamity - Arcane stack, mobility, and decent damage for T6.
• Skill 2: Frost Nova/Frozen Mist: Cold stack. This skill doesn't use a spell animation so it saves some time. It won't, however, allow 100% uptime on the cold stack (11 sec CD, 6 sec TR stack duration). You could potentially swap this out for something like Blizzard/Snowbound if you don't like the downtime on your stacks.
• Skill 3: Explosive Blast/Flash - Lightning stack. Use before TPing into an elite pack for a little extra punch. Mostly a utility spell to keep up TR stacks though.
• Skill 4: Storm Armor/Power of the Storm - Sorely needed AP cost reduction.
• Passive 1: Astral Presence - AP regen yet again.
• Passive 2: Glass Cannon - It's only T6 after all...
• Passive 3: Dominance - ... but just to be safe.
• Passive 4: Audacity - Multiplicative damage boost which synergizes well with this melee-range build.

Build tip: Set Explosive Blast and Frost Nova to auto-cast if you don't want to bother managing those.
