Druid
ShamanThis build runs 
Falling Thunder as a main skill to delete everything as it also clears off screen!
It is very Crit reliant to one shot enemies and needs a good Power Charge generation.
FLAT (NOT %) LIFE REGENERATION ON ANY ITEM IS MANDATORY TO IGNORE LIFE DEGEN FROM 
Berserk OTHERWISE IT WILL KILL YOU RUNNING 
Chaos Inoculation.
POWER CHARGE SUSTAIN
Main one being manual cast 
Profane Ritual which is smooth and easy in between the packs and provides constant charges in maps. You can put it in 
Cast on Critical for total automation if you have enough spirit.
Killing Palm is our other source and another one 
Thaumaturgic Generator anoint on amulet/helmet (for this you need mostly Int requirement skill gems to generate Power Charges).
You can also stick to the 
Sacrifice setup from Budget version in your Endgame Juicer to have the easiest time generating charges in Boss fights but it costs 60 spirit on both weapon sets.
SINGLE TARGET CHARGE GENERATION
Killing Palm will generate combos as it's a Strike ability for 
Mantra of Destruction that has Ailith's Chimes which then gives us Power Charges. Bosses have damage taken immunity on spawn anyway so it plays perfectly with the setup.
Combine all this with % Chance to not consume Charges ( 
Idol of Eramir, Boots suffix, Perpetual Charge, 
The Fabled Stag) AND % Chance to get additional Power Charge (weapon soul core, 
Thirst for Power) and you are winning!
DAMAGE SCALING
We use 
Crown of Eyes with 
Mystical Rage as Shaman has ascendancy for Max rage so combine all that with Battle Trance and it's totally crazy.
Could take it even further with 
Hateforge and 
Craving Slaughter (using 
War Banner to trigger it) but that is sacrificing a lot of Energy Shield from gloves slot.
