4-Player Push META

Trash Killer
Nova Necro, Natalya DH, Meteor Wiz, Scythe Necro

This position usually requires a build with good Area of Effect (AoE) damage like Death Nova or Meteor and huge temporary buffs like Arcane Attunement, Spellsteal, Assimilation etc. The main task is executing the damage rotation properly in order to progress through the Rift. With a double-support setup, the build must also be powerful enough to finish off the Rift Guardian by equipping Bane of the Stricken.

Rift Guardian Killer
Rathma Necro, Corpse Spider WD, Invoker Sader, Impale DH

The RGK requires a build that revolves around high single-target damage, often combined with fast attack speed skills to stack Bane of the Stricken.

Main Support
zBarb, zDH, zMonk

The main Support role requires good pull abilities, good overall damage & toughness boost. The main task here is to pull monsters together (for Area Damage value) for the Trash Killer, drag Elite packs along, scout the map and keep up damage & toughness buffs.

Secondary Support
zDH, zMonk, zNec

The second Support usually provides even more toughness and damage buffs to the group. The main task here is often very simple: Keep up all buffs while sticking close to the damage dealer. Sometimes the second Support also helps to scout the map and engage enemies.

Concept
During Season 32 there are two big builds when it comes to Trash Killing: LoD Death Nova Necromancer and LoD Meteor Wizard.

While these two builds have similar performance, their playstyles are anything but. Necromancer has a very short 12s rotation. He quickly casts several Death Novas decimating all trash monsters and dealing heavy damage to elites caught in the pull. The team then must quickly move all survivors forward and find more monsters for the next rotation, which is coming up in less than 10s.

The Wizard is the opposite of Necro - his rotation is very long - 32s. During that time zBarb must gather as many monsters as possible and group them all in one spot. Meanwhile, the Wizard, after some lengthy and complex preparation, casts a single Meteor (or 7 Meteors in reality) that deals downright unholy damage. If zBarb did a good job and there's enough monsters who are properly grouped, this Meteor kills absolutely everything and then team has almost half a minute to prepare the next pull.

The alternative to normal Trash Killer + Boss Killer team is to combine 2 Trash Killers that can also bring a decent amount of single target damage - in this case it's 2 Wizards. In such teams it may be wise to have at least one of them run with Bane of the Stricken to ensure a smooth boss kill, although it becomes unnecessary at hihger Paragon where Rift Guardian's average life expectancy is under 10s with a Power Pylon.

The Trash Killers are supported by a zBarb pulling Elites and grouping monsters together with Ground Stomp Wrenching Smash. On top of that, the Barb provides massive toughness buffs with Ignore Pain Mob Rule and War Cry. Additional offensive and defensive buffs are provided by the zDH.

Concept
If you want to delete the Rift Guardian smoothly and consistently it's best to recruit the help of yet another Necromancer, this time specialized in single target damage.

Rathma Army of the Dead Necromancer is by far the best boss killer in Season 32, capable of killing the Rift Guardian in a couple Army of the Dead casts at higher Paragon. If your Trash Killer happens to be not a Necromancer, then Rathma RGK also brings Frailty to the party which is a powerful group buff.

There are other RGK builds that can kill the boss relatively quickly but none come close to the raw power of Rathma and none bring anything significant to the party other than their damage.

As an RGK, simply follow the team during the Rift, try to pull enemies along and survive as much as you can. Your time to shine is on the Rift Guardian where you can unleash your full potential.

Concept
The Trash- and Rift Guardian Killer are supported by a zBarb pulling Elites and grouping monsters together so that their team can hit many targets at once. On top of that, the Barb provides massive toughness buffs with Ignore Pain Mob Rule and War Cry. Additional offensive and defensive buffs are provided by the zDH.

Gameplay zBarb
The standard zBarb play around the Trash Killer's Convention of Elements rotation, aggros and pulls monsters with Ancient Spear Rage Flip and pixels enemies with Ground Stomp Wrenching Smash.

Gameplay zDH
During DPS windows, make sure you apply all your buffs/debuffs properly (Multishot every 3 seconds, spread out Guardian Turret and spam Entangling Shot or Strafe). Try to help out the group in other ways, e.g. breaking walls with Bottomless Potion of Kulle-Aid, taking Wormholes that might spawn in dangerous places, etc. Especially on large pulls, make sure you re-apply Entangling Shot often and early enough.
