This is the Michael Jackson build for farming mp10.
Stylishly utilizes all three shouts, two spins, and the lightning effect of overpower.
Just put on some Thriller, and start farming Act 1.
Passives are Weapons Master, Ruthless, and Brawler.
Runes are Rend: Lacerate - Whirlwind: Volcanic Eruption - Threatening Shout: Demoralize - Battle Rage: Into the Fray - Overpower: Killing Spree - Warcry: Hardened Wrath
Strategy used is no movespeed, and follower has no vit so she is one shotted. She is still useful because she will res and drop her damage buff aoe and while dead she still grants the armor and magic find bonus. With her dead, monsters all follow closely to the barbarian who travels across the map spinning and rending. Ranged monsters are pulled with threatening shout into melee range, increasing the effectiveness of skills.
No ias or +average damage is used. 1.00 aps skorn. Focus on strength, cc, and cd to increase armor and the damage of rend: lacerate, which provides sustain and damage even when stunned or frozen. If 3% ls from belt isn't enough you could use the ls rune for rend but at the cost of dps. This is a cost effective build that has high reliability, no reliance on wotb, and is fun as 'hell'
Best place to farm with this build is act 2 oasis, but for this Thriller tribute, we will be running act 1. Efficiency and speed can be improved because as you can see I make many pauses for style and effect for your viewing pleasure. Enjoy.
