PoB (very conservative config): https://pobb.in/GhHbX2px2xwY

The build is pretty open when it comes to attacks or spells it can use, since it scales off charges. PoB seems to think 1 KB = 1 CoC, so the real dps is probably a fair amount higher. Void Battery was buffed with crit and attack speed, so that was where the build idea came from.

Pros:

• ALL THE CHARGES. Currently 13 frenzy, power, endurance and brutal charges.
• Reasonably tanky for how little life it has
• Speedy
• Very good recovery because of 1800+ regen, life on hit, leech, instant leech
• Capping crit without trying
• One button (plus movement)

Cons:

• Pretty expensive to find upgrades the more charges you have. It started feeling good around 10 charges.
• Oneshots. Not the highest max phys or chaos hits.
• Accuracy. I've currently solved this with precision.
• Hard to fit cooldown recovery rate, even though it's a CoC build, which limits dps somewhat.
