Build GuideThis build works amazingly well for high tiers of greater rifts - utilizing combinations of cold skills that slow, rockets with high damage, and skills + items that increase damage to slowed targets.
-Sentry (Spitfire Turret) -Your main source of damage. Spitfire Turret shoots multiple rockets at nearby enemies for 120% weapon damage (increased 100% by Ballistics passive)
-Companion (Wolf Companion) -Doesn't matter what rune you use, with Marauder's 4set bonus you get the whole zoo. Grants slowing of enemies and 30% damage boost among other benefits for short period of time when cast.
-Cluster Arrow (Maelstrom) -Your main attack to boost through items. Deals large amount of initial damage, plus shoots up to 5 rockets that hit for 450% weapon damage each (increased 100% by Ballistics passive)
-Multishot (Arsenal) - Another source of huge damaging rockets. Shoots 3 rockets for 300% weapon damage each (increased 100% by Ballistics passive)
-Elemental Arrow (Frost Arrow) -Provides an additional source of 'chilled' slow effect to up to 10 targets and dealing a decent amount of damage.
-Vault (Tumble) -Purely a mobility skill. Tumble allows more Vaults to be cast in a short period of time.
-Ballistics -Increases rocket damage from Sentry, Multishot, and Cluster arrow by 100%
-Cull of the Weak -Increases damage by 20% to slowed or chilled targets (almost all enemies will be hindered, so free 20% damage)
-Custom Engineering -Allows a 5th turret to be placed (assuming you have Bombadier's Rucksack) for more attacks + rockets. Alternative for lower tiers that dont require as many sentries could be Steady Aim (20% damage increase if no enemies within 10 yards)
-Ambush -Allows a massive damage burst for first few hits.
Marauders 6 set bonus (this is required - and the best way to obtain 6 set in my opinion):
Head: Marauder's Visage
Shoulders: Marauder's Spines
Torso: Marauder's Carapace
Legs: Marauder's Encasement
Feet: Marauder's Treads
Ring 1: Ring of Royal Grandeur(requires socket)
Rest of the gear:
Amulet: Hellfire Amulet - will probably be the best option should you be able to roll a decent one. If not, any of the 'defensive' amulets will do the trick allowing you to strike off a few affixes from elite packs. Main thing you want here is Dex, Critical Hit Chance, Critical Hit Damage, and socket.
Ring 2: Unity -Using a Unity on yourself and follower will halve all damaged recieved should your follower be using the Relic that allows him not to die. If playing in a multiplayer game, Stone of Jordan is a viable option. Grab a socket here as well.
Belt: The Witching Hour -Best damage belt in the game, although rare. Hellcat Waistguard is another viable option due to attack speed + elite damage.
Wrists: Reaper's Wraps -Will provide extra hatred from health globes, though not really required as hatred shouldn't be much of an issue. Slave Bonds now rolls with 5 primary affixes, enabling a more defensive bracer with both vitality and all resist (instead of having to choose between the two)
Gloves: Tasker and Theo - The pet attack speed bonus on these gloves is invaluable. By far best in slot, also extremely rare. Magefists are a viable second option. increasing the damage of rockets from Spitfire Turret and Multishot.
Weapon: Etrayu - This bow now rolls will Cold Damage % making it superior. Kridershot will allow for a more player-active playstyle with Elemental Arrow. If neither are an option, any high damage crossbow such as Manticore or Hellrack will do the trick.
Off-Hand: Bombadier's Rucksack - Best in slot, allowing 2 extra sentries. Would not recommend anything else.
-Enforcer - Increases the damage of your pets by xx.xx% damage. This includes the Zoo as well as Sentry damage itself.
-Bane of the Trapped - Increases the damage of movement impaired enemies by xx.xx%. This includes slowed and chilled enemies from your cold skills.
-Bane of the Powerful - Increases damage by 20% for xxx seconds after killing an elite pack. As a bonus also increases elite damage by 15% at rank 25.
