Havoc Demon Hunter DPS Liberation of Undermine Raid Guide — The War Within (11.1.7)

Vexie and the Geargrinders is an AoE fight in the primary phase, with a single-target burn intermission. As Havoc brings a lot of built-in cleave, going for a single-target focused build and using adds for funnel into the boss with Aldrachi Reaver is best suited here.

• Use Blur if targeted by Spew Oil as you will get hit by the initial pool landing. Have charges of Fel Rush saved for this as well to drop it in a good position.

• The burn intermission is generally triggered around the 1m45s spot by most groups, meaning you can safely send Metamorphosis on the pull and have it come back up during the burn phase.

• Focus target a Pit Mechanic during the intermission so you can interrupt Repair without switching targets.
• Make sure to keep Reaver's Mark applied to The Geargrinder to funnel any AoE damage into it via Wounded Quarry. This is especially important during the burn where you can make use of the pit crew adds.

The Cauldron of Carnage combines a single-target main phase and a 2-target cleave intermission, repeating until the encounter is complete. Havoc brings enough built-in cleave with a single-target build to cover the intermission, so the higher throughput Aldrachi Reaver is recommended.

• There are no specific defensive requirements for this boss, so use Blur freely when you feel unsafe. Use Netherwalk if you are caught in a bad spot on either side.

• Metamorphosis should be on the pull and then on cooldown. You should also hold it briefly at the 4 minute mark to align it with the third Colossal Clash for extra cleave damage on both bosses.

• For the Flarendo side you need to actively dodge a lot of mechanics, so use Fel Rush carefully if you're in a bad position, and avoid dashing into other waves.
  • If targeted by Blastburn Roarcannon, have a charge of Fel Rush ready so you can get out of the beam after targeting it away from the raid.
• For the Torq side you need to be much more careful with movement to avoid being stunned. Stutter step during Thunderdrum Salvo to avoid the swirlies while avoiding a lethal stun. Be very careful using movement tools like Vengeful Retreat here as it still builds up the stun meter.
  • Use Chaos Nova and Fel Eruption if necessary on loose Voltaic Images to avoid them reaching other players as well.

Rik Reverb is predominantly a single-target encounter, however the add spawns triggered by Sparkblast Ignition need to die as quickly as possible to avoid a wipe. Havoc's single-target loadout brings enough tools to cover this, so a standard Aldrachi Reaver build works best.

• Use Blur if assigned to soak Lingering Voltage. If not, make sure to use it if targeted by Faulty Zap.

• Eye Beam should naturally line up with Sparkblast Ignition spawns without much deviation, so aim to use it on the largest firework clump you can. Still try to maintain Reaver's Mark on the boss to funnel some extra damage into the boss.
• Each intermission comes at the 2 minute mark, meaning you will always have some drift on your Metamorphosis cast. Only ever use one cast each phase, as most of it will be wasted by Sound Cloud if you try to squeeze a second in.

• Be careful of positioning to avoid the Sonic Blast frontal, especially when using Vengeful Retreat.
• If you can't reach an amplifier comfortably you can use Double Jump to get over the Blaring Drop rings.

Stix Bunkjunker has single-target as the most important aspect, but frequent add waves that require burst AoE to avoid them overwhelming the tank is very helpful. Havoc's natural cooldown timers work out perfectly for this anyway, and Aldrachi Reaver can also leverage these for funnel.

• There are no specific defensive requirements for this boss, so use Blur freely when you feel unsafe.

• Eye Beam should be used liberally throughout here, as most add waves spawn quite far apart. You should be able to use one cast to break Territorial on a Territorial Bombshell and have it come back in time for the add wave to be dumped by Rolling Rubbish.
• Use Metamorphosis on the pull and on cooldown after, ideally for as much boss damage as possible. Hold it briefly during Electromagnetic Sorting at 4 minutes in case you get picked.

• Have a charge of Fel Rush saved to get out of the Trash Compactor slam comfortably at the end of the intermission.

Sprocketmonger Lockenstock is a pure single target encounter that has a large amount of movement throughout, so a standard Aldrachi Reaver build is recommended.

• Blur is best saved for the intermission as healers will be busy moving to get into position, and raid damage is high.
• It can be difficult to get good value out of Darkness here as the raid is regularly spread out, but placing it under the boss during the intermission where the melee will stack is your safest bet.

• Metamorphosis should be used on the pull and held briefly every 2 minutes for the intermission cast. Use it alongside other cooldowns as soon as you get back to the boss during Beta Launch.

• Fel Rush and The Hunt can be used to dash to the boss in the intermission, but beware your hitbox is active while travelling.
• Using Double Jump will pause the conveyor belt momentum change so use this to path to the boss quickly throughout the fight. Also use it to avoid falling down the two holes in the middle.

The One-Armed Bandit is a long encounter split between a phase with extremely high priority adds and a pure boss burn. Due to how important burning the adds down are in the first phase, Havoc's natural cooldown cycle plus funnel is perfectly suited.

• Blur is best saved for the most dangerous combinations involving the Flame coins that deal raid-wide damage.
• Darkness is also very well suited here. Organize with your healers for the combination they need the most help with.

• Havoc should be able to very aggressively use Eye Beam and have it ready for every add spawn triggered by Spin To Win!. As soon as these waves spawn use Fel Rush to engage them as quickly as possible.

• Pay very close attention to Pay-Line spawns, both to gain the High Roller! damage buff by standing next to it, and to avoid being killed by standing in its path.
• Chaos Nova should be used specifically during Reward: Shock and Bomb to keep adds stacked for burst AoE.

Mug'zee is mechanically very complex, but there is not as much in the way of DPS optimization needed as they are all encounter specific things that need to interact. As the fight has a fixed 40% burn phase and no major adds to deal with, Aldrachi Reaver is well suited.

• Blur is best saved for soaking either Goblin-guided Rocket or Earthshaker Gaol, as these initial hits cause heavy raid damage.

• Metamorphosis should be used on the pull and on cooldown during the main phase.
• As you approach 40% and the 4-minute mark hold Metamorphosis for the first Static Charge and use it immediately as he arrives at the first charge spot. This should allow you to squeeze in a second cast before the final hard enrage at the end.

• While there are a lot of add spawns, it is hard to get much cleave value as Unstable Crawler Mines are immune and Earthshaker Gaol will be split. Aim to have Reaver's Mark on Mug'zee at least throughout to get some extra value from Wounded Quarry if you ever swap.
• Use Fel Rush to keep up with the boss during Static Charge, but be careful in your direction to not be caught in the two cones.
• You cannot double jump out of the Earthshaker Gaols.

Chrome King Gallywix is predominantly a long single-target encounter, but add waves that spawn are important to kill very quickly. Havoc naturally brings solid burst AoE in its toolkit, and any extra taken is overkill so a standard Aldrachi Reaver single target build suits it very well.

• Blur has a lot of places to be used, and often healers will tell you when they need defensives due to the massive raid damage intake.
• Both the Scatterblast Canisters and Fused Canisters in Phase 1 and 2 respectively apply Mechengineer's Canisters. These raid soaks are excellent spots to use Darkness on, so plan around this with your healers.

• Metamorphosis should be used on the pull, with a brief hold:
  • Hold until the first add phase is over at roughly 2 minutes, using it when the boss moves to the edge of the platform.
  • You can opt to hold the third cast for the upcoming add wave spawn after the TOTAL DESTRUCTION!!! cast if your raid needs additional burst AoE.
• Both The Hunt and Sigil of Spite can be held for add wave spawns if needed to guarantee Reaver's Glaive triggers.

• Be very careful using movement tools on this fight as there are both a lot of lethal mechanics you can bring into the raid, get hit by, and a very big hold in the middle you can fall into.
• If using The Hunt to the boss on the edge of either of these from just outside of melee range, it will place you right on the edge, so make sure to stand still!
• Avoid Precise Sigils on the fight as it causes them to spawn at the bottom of the hole in Phase 1, not triggering any soul generation or damage.
