The Destructive Crossbow - Dusk Deep
For Demon Hunters, Dusk Deep defines the pinnacle weapon for Zir. Its 6-piece bonus grants Night Stalker, summoning a darkness zone that deals 3000% weapon damage per second to all enemies caught within. With proper positioning and crowd control, DHs can cripple Zir's health bar rapidly inside this debuff zone.
Bonuses like grouping enemies, slowing missiles, and dealing physical damage synergize perfectly. Top tier DPS allows bursts when safe and sustained strikes during dangers phases. For any DHs lacking this set, buying a Dusk Deep powerleveling carries you straight to victory.
The Sorcerer's Orb - Primeval's Soul
As one of the most lethal farming builds, Primeval's Frozen Orb Sorceress excels against even Abattoir's final boss. Its 4-set bonus releases three powerful comets that orbit players, dealing 650% weapon damage per second to all enemies within 15 yards without D4 gold.
Combining enormous damage potential with wide range control through Freezing abilities stunlocks bosses endlessly. Seeking safety behind mercenaries and Teleport keeps Sorceresses shielded during casts too. Together, Primeval's tools dismantle Zir's aggressive assaults like no other class.
The Arcane Catalyst - Tal Rasha's Elements
Among options enabling pure elemental builds, Tal Rasha's excels through versatility. Cycling between damaging skills grants 4,000-6,000% weapon damage buffs. Used optimally around Zir, this repeatedly stacks high multipliers on basic abilities.
Topping off damage with Orb, Meteor or Hydras while proccing defensive Fire/Cold Armors maintains consistent, ranged pressure. With enough cooldown and mana regeneration, immunity uptime outlasts even the deadliest stomps with room to spare too.
The Barbarian's Reaver - Legacy of Dreams
As the quintessential Whirlwind build, LoD Barbarians cleave through enemies in tornadoes of destruction. Its 6-piece grants up to 800-1000% increased damage per enemy hit by Whirlwind, multiplying further against huge packs.
Chaining together elite mob densities grants unmatched burst potential. Combined with armor-ignoring damage, short cooldown warcries like Battle Rage and damage taken redistribution, these Barbs endure even Abattoir's toughest trials with lifesaving fury.
The Necromancer's Wand - Inarius' Visage
Necromancers control crowds with bone spears, raise armies of dead with Corpse Lance and can even revive downed allies. But Inarius' true strength lies in its 6p bonus. Consuming corpses heals for 80,000% of Corpse Lance damage with no cooldown, sustaining indefinitely against Zir's hard hitting abilities.
Bone Armor grants damage reduction and Bone Shield redirects damage. Together with supporting Revive minions as meatshields, Inarius Necros become unkillable juggernauts dominating even the deadliest endgame challenges with utter dominance and longevity few can match.
Other Viable Options
While the above sets stand among top options, other powerful choices exist too. Sunwuko Monks combining sweeping winds, cyclone strikes and Mystic Allies outlast anything. Raekor Barbarians unleash primal damage. And Zodiac crusaders spam Cooldown-free Bombardments continuously.
With effort, optimized legacy crafted sets, unique legendaries or even hybrid/support roles applying complementary buffs let determined players succeed however they specialize. Don't lose hope - where player skill makes up ground, any approach remains viable given patience and teamwork.
Augment Your Miracle With Upgrades
Maximizing chosen builds requires highly optimized gear. Consider usingD4 gold for item services targeting legendary powers matching playstyles precisely. Services let experts assessing strengths accelerate progress focused. Within ethical standards, upgrading speeds reaching full potential necessary to take on final challenges. Combined with communal knowledge, even impossible seems surmountable.
Master Your Weapon's Synergies
Sets alone mean little without understanding symbiotic interactions. Study skill runes/items synergizing specific playstyles. Unlocking full potential demands recognizing unintended layerings doubling damage. Subtle item quirks differentiate mediocre set users from masters. Approach Abattoir prepared to leverage every hidden facet rather than brute forcing through skill alone. Knowledge lights pathways others consider unpassable.
Stay Determined!
Trials will push limits, but where will finds way. Countless triumphed using means considered impossible. When walls seem insurmountable, reflect how far journey brought instead of how far left to travel. Small conquerings each try strengthen resolve compounding into victory through perseverance where immediate success evades. There, true glory found enduring despite all saying 'No' until prevailing nonetheless in the end through own strength alone.
Have Faith in Your Build and Team
Doubting potential saps motivation critical to challenging limits. Believe in build mastery and ability cooperate overcoming seemingly unfavorable odds. Coordinated groups turn average on paper into legend through shared resolve weathering any storm.
With right companions and firmly in abilities, unthinkable becomes ordinary. Stay confident facing Abattoir - destiny remains unwritten until final blow delivers judgment. Then emerge victorious through strength of will powering on despite knowing 'failing is an option'.
