Barbarian Frenzy Boss Killer Build Guide for Raids

This build specializes in boss takedowns for content like the Helliquary, Kion's Ordeal and Path of Blood, shifting its focus away from enhancements of speed and utility associated with the usual farming builds. Instead, it leans into survivability and out-healing the damage you take through a combination of Frenzy, Wrath of the Berserker, and Undying Rage. Depending on the legendaries at your disposal, you can either improve your tankiness with Hammer of the Ancients summons, or get emergency mobility from Furious Charge.

If you are interested in approaching a different type of content, please see our other Barbarian builds below.

Buff maintenance is the most important aspect of the build, as you need to watch for telegraphs and projectiles to determine incoming burst damage from bosses, ideally applying Undying Rage right before in order to proc its effects, and then playing defensively until it comes back up. Constantly chip away at the Boss with Frenzy, unless you need to move to safety due to Undying Rage downtime or other factors. Use Demoralize offensively, as the power of Battlemaster's Helm will improve the damage dealt by yourself and your allies. The last part of your rotation depends on whether you have taken Hammer of the Ancients for the summons from The Remembered, or play with Furious Charge for the extra escape options. With HotA, simply reapply the (potentially two) Summons and enjoy their considerable tankiness and damage. With Charge, you need to pay extra attention to Boss attacks and adapt accordingly — either engaging or disengaging with the skill.

Primary Skill: Frenzy seems to be designed to be played around high Restless Demon uptime, offering a consistently available Ultimate asset with legendary gem combinations of Zod Stone and Ca'arsen's Invigoration. It is otherwise a single target-oriented Primary Attack powerhouse that is hard to fit in other content, but finds its rightful place during Boss takedowns.

Damage Buff: Demoralize is a group skill powerhouse due to the legendary powers of Battlemaster's Helm. Note its considerable cooldown compared to the length of its effect, and try to time its use according to the needs of the party (if you are in one), ideally coordinated and synced with the burst cooldowns of others.

Attack Speed Buff: Attack speed is decisive during Boss fights, and few buffs compare to the ubiquitous Wrath of the Berserker. While the skill requires a lot of supporting legendary effects to truly shine, its innate versatility makes it part of many Barbarian setups.

Survivability Buff: Undying Rage is a survivability powerhouse, allowing you to endure massive bursts of damage through simply out-healing them. This becomes increasingly valuable in progression forms of content like Challenge Rifts and especially Helliquary, as well as PvP situations where you need to outlast the burst coming your way as you close the distance to the enemy. In the Diablo Immortal beta, it had no supporting legendaries, but was still deemed a valuable addition to Barbarians.

Secondary Damage Dealer: Despite its baseline mobility functions, Furious Charge is also a hefty nuke — providing you with a dashing skill that also deals heavy damage along its path. Dashing skills will always be useful in challenging PvE content, since you will need ways to get out of harm in a pinch.

Alternative: Another amazing option for a secondary damage dealer is Hammer of the Ancients, particularly if enhanced by the powers of The Remembered. The Ancient summoned by the legendary packs a punch, offering crowd control, damage, and tanking substantial damage of his own. You can further lean into your newfound summoner powers by using Davin's Legacy, which adds a second charge to HotA — ergo, a second Ancient.

Equipment is split into Primary (right side of character screen) and Secondary (left side).

Primary equipment includes the Main-hand, Off-hand, Head, Shoulders, Chest, and Legs slots of your character sheet. These slots can — and should — be filled by Legendary items, since their legendary powers and ability to be socketed with Legendary gems vastly overpowers lower tier gear. Of course, these slots will be temporarily filled with Common (Grey), then Magic (Blue), and then Rare (Yellow) gear, before graduating into Legendaries (Golden).

The suggested Legendaries for Frenzy Barbarians are:

• Main-hand: Stonefall — This legendary axe increases Hammer of the Ancients damage by 10%, improving your only other source of DPS outside of Frenzy. That being said, this recommendation is applicable only if you use HotA in the first place; you can simply use your best rolled Main-hand weapon instead. At the high end of character progression, you can consider The Maddening, whose Awakened effect increases Frenzy damage by 10%.
• Off-hand: The Remembered — This legendary axe adds a summoning aspect to the use of Hammer of the Ancients, spawning a Spirit of the Ancients minion with considerable damage and tanking capabilities. If you opt for a Furious Charge variant instead, consider options like Broken Soul or Fearhammer to augment your damage dealt.
• Head: Battlemaster's Helm — This legendary helm replaces the base effect of Demoralize with a War Cry that improves the damage you and nearby allies deal by 25%. Whether you're in a group or not, shortening the Boss fight with additional DPS is always a good idea.
• Shoulders: The Coming Storm — These legendary shoulders reduce the Wrath of the Berserker cooldown by 15%, with an Awakening enhancement that cuts the cooldown even further More time spent with the valuable WotB active will greatly improve your chances of success.
• Chest: Davin's Legacy — This legendary chest provides you with another charge of Hammer of the Ancients, turned into a potent combo of a nuke and a summoner skill via the interaction with The Remembered.
• Legs: Screaming Fury — These legendary pants allow you pinpoint accuracy at the point of impact, and add a crowd control aspect to Furious Charge. This specific Legendary is not required however, and you can use your strongest rolled item for the slot.

Secondary equipment includes the Amulet, Rings, Hands, Waist, and Feet slots of your character sheet. These slots can — and should — be filled with Set items, since the bonuses they form once completed vastly overpowers lower tier gear. Of course, these slots will be temporarily filled with Common (Grey), then Magic (Blue), and then Rare (Yellow) gear, before graduating into Sets (Green). Secondary equipment can only be socketed with Normal gems.

The recommended Set for Frenzy Barbarians is War Rags of Shal'baas, which increases Primary Attack damage and attack speed. The set consists of:

• Storm-Tack of Shal'baas (Waist) — Farmed at Forgotten Tower in Difficulty Hell I and above.
• Wind-Trods of Shal'baas (Feet) — Farmed at Tomb of Fahir in Difficulty Hell I and above.
• Dozen Strikes of Shal'baas (Hands) — Farmed at Mad King's Breach in Difficulty Hell II and above.
• Burning Heart of Shal'baas (Neck) — Farmed at Pit of Anguish in Difficulty Hell II and above.
• Resting Fangs of Shal'baas (Ring 1) — Farmed at Temple of Namari in Difficulty Hell IV and above.
• Braided Serpent of Shal'baas (Ring 2) — Farmed at Cavern of Echoes in Difficulty Hell IV and above.

The set bonuses of War Rags of Shal'baas are as follows:

• 2-piece Set Bonus: Primary Attack damage increased by 15%.
• 4-piece Set Bonus: Your Primary Attacks gradually increase your Attack Speed, up to a maximum of 25%.
• 6-piece Set Bonus: Your Primary Attacks have a 5% chance to increase your Attack Speed for 10 seconds. Cannot occur more often than once every 30 seconds.

Improving your attributes in Diablo Immortal generally revolves around increasing the total amount of Combat Rating, or CR. Every primary attribute point (Strength, Fortitude, Vitality, Willpower, and Intelligence) grants you 1 point of CR.

The priority attribute for Barbarians is Strength, which gives +0.3 Damage per point; given otherwise identical options, use the one with higher Strength to increase your DPS. Second in the priority order is Fortitude, which adds to your Armor Penetration — indirectly increasing damage dealt by also improving your crit chance. This attribute suffers from diminishing returns due to crit caps, but is still quite valuable. Third in the priority order is Vitality, which simply increases your Life total; the longer you can stave off death, the better.

Stat priority order and stat benefits for Barbarians are as follows:

1. Strength — Grants +0.3 Damage to Barbarians, and +1 to your total CR.
2. Fortitude — Grants +0.1 Armor Penetration, which affects your crit chance. It also grants +0.1 Armor; Armor increases your Block chance, and blocking attacks mitigates 20% of the damage dealt. More mitigation is never amiss, and even more so when dealing with riskier content like the Helliquary. It also adds +1 to your total CR.
3. Vitality — Grants +3 Life; the more you can add to your total health pool, the better. This is especially true for melee classes like the Barbarian, and Barbs specifically thrive on percentage-based healing skills. This attribute also adds +1 to your total CR.
4. Willpower — Grants +0.1 Potency and 0.1 Resistance. Potency increases the duration of harmful effects that you inflict on your foes. Resistance lowers the duration of harmful effects inflicted by your enemies on you. This attribute also adds +1 to your total CR.
5. Intelligence — Grants +1 CR. This attribute does nothing else for Barbarians, and should be avoided as much as possible.

You should not put an emphasis on Special Attributes when considering between gear pieces. This is due to the overpowering importance of Primary Attributes and your CR total. That being said, the better Special Attributes are the two Crit Stats (Critical Hit Chance and Critical Hit Damage), Cooldown Reduction, Beneficiary Effect Duration, and Movement Speed. You can also consider Increased Damage to Players for PvP gear.

Pieces of Primary Gear that you upgrade at the Blacksmith attain up to three additional Bonus Attributes for Reforging at Ranks 6, 11, and 16. These Bonus Attributes belong to "families" (outlined and ranked below); a Family Bonus can be unlocked if all three Bonus Attributes are from the same family. Multiple Primary Gear pieces can have the same Family Bonus to improve your proc chance. The process of Reforging is done with the Reforge Stone consumable. Note that only Primary Gear pieces can be reforged; Secondary Gear pieces cannot.

1. Tremor Stone is the most valuable bonus for general content, as its Family Bonus adds a crowd control proc and extra damage to your Primary Attacks.
2. Vengeance Stone brings a single-target-oriented Family Bonus that becomes increasingly important as you push the difficulty of the content you are doing, i.e. Challenge Rifts. Pair it with high Attack Speed choices like Frenzy to have a chance at finishing off Boss fights within the timer.
3. Wildfire Stone is mostly valuable due to its innate attributes, as it brings valuable Critical Hit Chance to the table. The Hydra summon from the Family Bonus is mostly an extra minion to soak up damage.
4. Barrier Stone has a Family Bonus that brings some much needed mitigation to Barbarians, a class that face-tanks all of its damage. The absorption shield is paired with some excellent innate attributes like Damage Taken Decreased and Block Chance, which further reduce incoming hurt.
5. Jolt Stone offers situationally valuable bonuses; it has Beneficial Effect Duration Increased as an innate attribute, which is decent for groups, and a Cheat Death proc which is never amiss when soloing content. Its Family Bonus brings soft CC to attackers, which is decent mostly for PvP.
6. Ravager Stone offers summoner-oriented innate attributes that are all but useless to Barbarians (unless you hyper-specialize in Ancient summons). Its Family Bonus requires enemies to be slain to proc, significantly diminishing its usefulness when doing progression content like Challenge Rift bosses and Helliquary.

As per tradition for Diablo games, socketed gear allows you to insert beneficial gems according to your needs. In Diablo Immortal, gems are divided between Normal Gems (socketable in Secondary Gear) and Legendary Gems (socketable in Primary Gear).

Normal Gems can only be socketed in Secondary Gear. Normal gems are divided into Red, Blue and Yellow sockets, and their priority is listed below. Priority-wise, gems are decent power increases to your character, but should never come at the cost of Primary Attributes and your CR score. Go for Red and Blue gems over Yellow if possible, as they provide a stronger bonus overall.

• Red Sockets: Prioritize Tourmaline as it provides a straight Damage increase. Ruby is also decent for the Life increase, but only if you lack Tourmalines.
• Blue Sockets: Prioritize Sapphire, which increases your Armor Penetration, and your Critical Hit Chance stat as a result. Note that Crit Chance provided from Sapphires has diminishing returns, capping out at 33%; when benefits from ArPen get too insignificant, swap to Aquamarine. Aquamarine provides Armor, which is a decent source of damage mitigation.
• Yellow Sockets: Prioritize Citrine for the Potency gains, increasing the duration of harmful effects you inflict on enemies; however small its benefits, they trump the Resistance effects provided from Topaz.

Legendary Gems can only be socketed in Primary Gear. They provide unique and very powerful bonuses on top of a robust stack of stat increases. Legendary Gems are found in Elder Rifts enhanced by the Crest consumables, as well as through crafting at the Jeweler in Westmarch.

Early on in Barbarian character progression, you should use common, 1- and 2-Star Legendary Gems like:

• Fervent Fang — Can be obtained from the Battle Pass, saving you some Crests. Provides a stacking damage increase against a target with successive attacks; great for single target damage.
• Ca'arsen's Invigoration — Half of the Primary Attack-Ultimate combo, this gem increases the speed and damage of Primary Attacks, fitting nicely into a Frenzy-centric build.
• Zod Stone — The other half of the Primary Attack-Ultimate combo, this gem increases the duration and damage of Ultimate skills, allowing for unparalleled uptime of Restless Demon.
• Power & Command— When timed correctly, this gem will provide a decent boost to your Primary Attack damage. Note its rotating bonus, alternating between Primary Attack- and Cooldown-boosting at 9 second intervals, and try to fit your HotA usage (if the skill is present) in the Cooldown half of its bonus.
• Lightning Core — Despite its low proc chance, this damage-dealing gem can wipe out entire packs when activated, or focus down a larger foe, making it a decent addition to you legendary gem lineup.
• Berserker's Eye — This gem increases damage dealt at the cost of an increase in damage taken. For most of the farming PvE content, this is a reasonable trade-off that you can feasibly mitigate with the Barbarian's strong sources of self-healing. If you do not fancy the increase of risk, an alternative for this slot is the pure damage mitigation of Battleguard.

When perfecting your character for endgame content, the 5-Star Best-in-Slot Legendary Gems for Barbarians include:

• Blood-Soaked Jade — With its Damage and Movement Speed increases, it is largely considered to be the best legendary gem in the game for pretty much all forms of content.
• Seeping Bile — The value of this gem scales with the number of attacks you inflict, fitting well into Attack Speed-heavy Barbarian builds. With a considerable damage proc and a spreading effect, it is one of the best additions to your legendary gem lineup.
• Frozen Hearth — With percentage-based mitigation against ranged damage, this is one of the strongest defensive legendary gems you can support your character with.
• Blessing of the Worthy — Barbarians thrive at melee ranges and sustain a lot of attacks, making the retaliation proc of this gem quite valuable. Note its scaling off maximum Life, which turns the Barb's considerable health pool into a makeshift nuke.
• Chip of Stone Flesh — This is a PvP powerhouse of a gem, inflicting hard CC and increasing damage dealt on affected targets. It also provides decent value for progression content.
• Phoenix Ashes — A cheat death proc is never useless; considering the damage intake Barbarians have to deal with in progression content, its value grows even more.

Paragon Points are character-specific progression system that allows you to advance in power after you reach maximum level. Each level gives you a Paragon point to spend into currently available nodes on the five Paragon Trees. While Paragon Trees are specialized for certain tasks, you should always keep in mind the tenets of character building — increasing damage and mitigation as much as you can. With that in mind, focus down the Vanquisher tree first, pick up the experience bonus from the Treasure Hunter tree, pick up whatever is useful from the Gladiator tree, and finish off with the group powerhouse of the Soldier tree. Always keep in mind that the (circular) Persistent Attributes are always active once leveled, but the (square) Specialization Skills are only applied when their respective Paragon Tree is active.

• Vanquisher Tree: The offense focus of this tree makes it the best starting point for all characters. It is recommended that you start with the middle row, maxing out Damage and picking up Zeal. Go down the bottom row, maxing out Damage and picking up Wrath. Finally, go along the top row, maxing out Potency, putting the point in Exorcism, and finishing off with Deeper Pockets and Heart of Wrath. This puts you at Paragon level 49.
• Treasure Hunter Tree: This tree unlocks at Paragon 50 and focuses on rewarding you more for your grinding efforts, making it an attractive mid-progression pickup. Go through the middle row, maxing Armor to attain Swift Learner. Then go on straight by maxing out the Damage node. This puts you at Paragon 70.
• Go back to the Vanquisher Tree. Max out the Life nodes in the mid row that follow Zeal, and put one point in Judgment to finish off that row. Then, go to the bottom row and put 3 points into Armor Penetration, which puts you exactly at Paragon 99.
• Right around this point, you have a decision to make. If you focus on PvE content, you should divert your attention back to the Survivor Tree — the other tree unlocked by default. Start out by maxing Life, picking up a point in Unyielding and progressing downwards. Max out Armor, then through the middle row — taking Escape Artist, additional Life, and Precognition along the way. Finish off with the coveted Damage increase. If you focus on PvP content, you should focus on the Gladiator Tree instead; this tree unlocks at Paragon 100, and offers brawling-oriented bonuses. Start off with maxing Armor Penetration, picking Uncontrollable right after it and continuing upwards. Max out Life, attain Quick Witted, and go into maxing Resistance and the second Life node. Get the Cheat Death right above the Life node. Finish with the consistently desirable Damage.
• At this point, you are hovering around the Paragon 180-185 point. One thing to consider is going back to the Vanquisher Tree to finish off the bottom right Armor Penetration node. You can also divert to the Treasure Hunter Tree to grab Gold Find and its subsequent Armor Penetration node. Alternatively, if you group up a lot, you can tab over to the Soldier Tree. This tree unlocks at Paragon 150 and is focused on grouping bonuses and provides tremendous utility for most modes of play. Take Hold Formation and head down to Resistance, then even further down into Damage. Attain the full bottom row — Battle Morale into Armor Penetration into Sacrifice. Then, finish off the middle row with Combat Veteran and Potency. Finally, go through the top row of Life and First Aid.

It is important to reiterate that your utmost priority is picking up all the damage nodes you can, deviating into one tree or another only to further that goal. Secondary valuable pickups are found in Armor Penetration and Life nodes. Once you are done with leveling all the Damage nodes, you are free to fill out Paragon trees as you see fit, as well as to activate specific Trees for the needs of the content you are doing.

When you turn in Bestiary pages, you will receive a class-specific consumable. For Barbarians, this item is the Horn of Arreat, which increases all damage done by yourself and your nearby allies by 10% for 20 minutes. Be generous with its use, especially in party content; buffs like these are what make the Barbarian an invaluable member of the group.
