Arachyr Firebats Witch Doctor Guide


Arachyr Firebats Solo Push
View all variants

Firebats is a well-known Witch Doctor skill, used all the way back before Seasons. Further down the road, it has been the META Trash Killer of choice from Season 7 to 9, juggling between Helltooth and Spirit of Arachyr sets.

The latter provides a generic damage multiplier to all Creature skills. In this build we combine this damage boost with the iconic Firebats channeling playstyle and crazy Attack Speed values from the Staff of Chiroptera and Pain Enhancer.

Out of all creature skills, Firebats has the most damage potential with its Attack Speed scaling potential paired with channeling buffs from Taeguk and Mantle of Channeling. On top of that there are high damage multipliers available from Staff of Chiroptera and Bakuli Jungle Wraps.

During Season 24, Ethereals brought an impressive damage potential buff to the setup due to the breathtaking Attack Speed granted by Ghostflame. In Season 25, the build didn't get any benefit from the Spirit of Arachyr rework, being completely outclassed by the new Arachyr Corpse Spiders.

This is an Area Damage (AD) build, since Firebats Cloud of Bats can proc it. This is further enhanced by the incredible Attack Speed scaling of the setup allowing you to melt monsters in high density (see Mechanics). While the build is fun to play, it lacks damage compared to the best performing Witch Doctor builds. Yet with this potential, it is not entirely excluded that Arachyr Firebats Witch Doctor becomes once again the META Trash Killer in the future! Anyways, let's get into it!

Core Setup

Core Item Build


  • You get 25,000% Firebats damage from Spirit of Arachyr (6) Bonus as well as 75% damage reduction from the Spirit of Arachyr (4) Bonus.
  • Staff of Chiroptera is one of the best items for this build giving 100% faster attacks (more details in the Mechanics section), 75% reduced Mana costs and 150% increased damage.
  • Bakuli Jungle Wraps give 300% increased damage as long as enemies are affected by Locust Swarm or Piranhas.
  • Lakumba's Ornament and Sacred Harvester give tremendous toughness and damage buffs by doubling our Soul Harvest stacks.
  • Ring of Emptiness provides us with a crazy 300% damage buff as long as the target is affected by either Haunt or Locust Swarm.
  • Ring of Royal Grandeur allows us to complement Spirit of Arachyr with Captain Crimson's Trimmings.

Season 27 Sanctified Items

Angelic Crucibles are new consumables that drop anywhere once you're Level 70. Using them on items reforges them into Sanctified Items with Primal Ancient stats, and adds one of three new unique Class Powers listed below. For full details on how they work, check out this Seasonal Guide by Chewingnom!

Let's look at our Class Powers and see how they apply to our build:

  1. The only power for us is the Sanctified Haunt since it allows us to pixelpull everything before dealing damage for insane Area Damage bursts.
  2. The Sanctified Horrify power is a decent damage boost but the pixelpull from Sanctified Haunt is a better option overall.
  3. The Sanctified Gargantuan power doesn't help us, so go for the one at the top.

Since you can only equip one of them, choosing the right item to craft it on matters! Great candidates are Weapons, Offhands, Jewelry or any item with an important multiplier. With that in mind, we recommend Sanctifying one of the following items:

  • Ring of Emptiness
  • Shukrani's Triumph
  • The Compass Rose

Global Stat Priorities

Firebats Attack Speed Breakpoints

Attack Speed provides insane damage benefits for this channeling build and we definitely want to reach certain Breakpoints (see Mechanics). Generally you always want to have 7% Attack Speed rolled on your weapon in this build as this bonus is calculated multiplicatively to other Attack Speed bonuses.

In group, the majority of our Attack Speed comes from the secondary effect of Pain Enhancer. This means we don't need to stack additive Attack Speed rolls on gear to reach the 3 frames Firebats Breakpoint with 47 Pain Enhancer stacks. In the Solo setup we take the Enchantress with Focused Mind to reach the 8 frames Breakpoint. The faster we attack the more Mana channeling Firebats drains. For that reason we need to use Haunt Draining Spirit in the Trash Killer variant and Spirit Walk Honored Guest in Solo Push to regain our Mana.

Cooldown Reduction is not mandatory for this build, but it's helpful to use a Flawless Royal Diamond in your helm and take a "free roll" on your shoulder for Spirit Walk uptime to move, avoid attacks and gain Mana with Honored Guest. We also gain Cooldown Reduction from Grave Injustice in Solo. Area Damage works with Firebats and all its multipliers so this is one of our most important stats to have all items expect amulet! In solo play, crowd control reduction is a valuable stat on your helm and jewelry to avoid interruptions as much as possible.

Assembling the Build

1. Do the Challenge Rift for the materials to cube Legendary Powers. You can complete this once a week for additional resources and we always update the guide for you!

2. Gather the full Spirit of Arachyr set. Each piece can be gambled from Kadala for Bloodshards. Do not salvage any duplicate pieces you find! Instead convert them to another part of the set with Recipe 4 in Kanai's Cube. If you have extra materials you can use Recipe 3 to craft the remaining pieces, but this is expensive and not recommended for new players.

3. Gamble from Kadala in this order:

  1. The full Spirit of Arachyr set
  2. Bakuli Jungle Wraps
  3. Lakumba's Ornament
  4. Shukrani's Triumph or any Legendary Mojo for the start
  5. Convention of Elements and Ring of Emptiness

4. Craft using Recipe 3 in Kanai's Cube in this order:

  1. Staves to get Staff of Chiroptera
  2. Ceremonial Knives to get Sacred Harvester
  3. Rings to get Convention of Elements, Ring of Emptiness and The Compass Rose
  4. Amulets to get The Traveler's Pledge
  5. Anything from the Gamble list in Step 3 that you haven't already acquired.

5. Do Bounties to acquire several important items for this build:

  • Act 1: Ring of Royal Grandeur
  • Bounty Turn In: Recipe for Cain's Destiny and Captain Crimson's Trimmings

during your DPS phases


  • Bane of the Trapped is the most common damage gem providing a flat 1.6 damage multiplier. Firebats has 15 yards range so in order to deal damage we have to get within the rank 25 effect on Bane of the Trapped of 15 yards anyways.
  • Taeguk grants up to 80% additive damage and 20% Armor, making it a great offensive gem since we are a channeling based build with Firebats.
  • For Solo Bane of the Stricken is needed to kill the Rift Guardian.
  • Pain Enhancer's secondary effect is our main source of additive Attack Speed in groups. We can hit the 3 frame breakpoint with 47 Pain Enhancer stacks, letting us attack insanely fast. With Locust Swarm Pestilence from Vile Hive you will have this bleed on every mob.


  • We use Firebats as our main damage dealer. Cloud of Bats is the only rune that turns this skill into an area of effect around the player, dealing large amounts of damage to monsters pulled together by Supporters or Piranhas Piranhado. On top of that Firebats Cloud of Bats damage is increased to 850% weapon damage after 3 seconds of channeling far outperforming every other rune in terms of DPS.
  • Horrify Frightening Aspect is a must-have for its 50% Armor buff.
  • Soul Harvest is used in combination with Lakumba's Ornament and Sacred Harvester. Together they offer great offensive (a massive boost to Intelligence) and defensive (Armor from Languish, All Resistance through Intelligence and Damage Reduction from Lakumba's Ornament) buffs.
  • Spirit Walk is mostly used for Movement Speed and defensive purposes but also can be used offensively by moving to an Oculus Ring. In Solo gameplay the rune Honored Guest together with Grave Injustice are essential to regenerate Mana to keep channeling Firebats.
  • Locust Swarm is recommended for all variants of this build to engage enemies, reduce their damage done by Cloud of Insects and maintain your Bakuli Jungle Wraps and Ring of Emptiness damage buffs.
  • In Solo Piranhas Piranhado is used to group up monsters. The debuff also stays up essentially forever with the Creeping Death passive.
  • In Group Haunt Draining Spirit is used to regain Mana in large pulls at high Attack Speed breakpoints. As Haunt stays up almost forever with Creeping Death, Draining Spirit will search for a new target if the affected enemy dies. Haunt has an unlimited number of targets and at high Attack Speed values quickly generates Mana to channel Firebats!


  • Creeping Death increases the duration of Haunt and possibly Locust Swarm to 120,000 seconds (2,000 minutes, or almost 1.5 days). It ensures Bakuli Jungle Wraps and Ring of Emptiness uptime.
  • Confidence Ritual is used for a multiplicative damage increase in close range combat using Firebats.
  • We can take one or two defensive passives especially for Solo. Choose Spirit Vessel as a "cheat death" or Swampland Attunement for an insane Resistance boost when fighting huge monster pulls.
  • In Solo Grave Injustice is used to reduce cooldowns of Spirit Walk Honored Guest to regain Mana and Piranhas Piranhado to pull enemies together for area of effect damage while channeling.
  • In group, we take in Gruesome Feast for this last passive slot as it is one of the best passives in the entire game if you have a supporter like the zBarb providing you with Health Globes using skills like Threatening Shout Grim Harvest.

Patch 2.7.0 revamped the follower system giving all 3 hirelings new powers and the emanate system. The first thing you should do is read our complete follower guide and remember the key takeaways:

  1. The emanation system allows followers to share certain legendary and set powers with you. The most important ones are: The Flavor of Time, Nemesis Bracers, Avarice Band, Sage’s Journey and Cain’s Destiny. Click the guide above for the full list.
  2. Follower’s powers are based on their main stat (maxed at 25,000, but they have a 2.5x multiplier so you only need 10,000). This means we stack Intelligence on the Enchantress, Dexterity on the Scoundrel and Strength on the Templar.
  3. Guardian's Jeopardy (3) Bonus works for followers by improving their inherent stat multiplier from x2.5 to x3.5, making it slightly easier to hit the 25,000 main stat threshold if needed.
  4. Followers share 20% of their Experience, Magic and Gold Find stats with you.
  5. Legendary gems do not work on followers, except Esoteric Alteration and Mutilation Guard.
  6. Cooldown Reduction does not work for any follower skill except the Templar’s Heal.
  7. Followers never deal significant damage; you’re on your own to clear the content.

Select Follower


Start off by using Spirit Walk to run towards enemies and use Soul Harvest Languish to get the offensive & defensive buffs up. Cast your Locust Swarm to DoT up monsters and group them up using Piranhas Piranhado. Always cast Soul Harvest when you are in close combat and the skill is off cooldown. Stand on the Spider Queen's Web to get the Spirit of Arachyr (4) Bonus toughness buff.

Cast Firebats to spawn an Oculus Ring and move there using Spirit Walk for the additional damage buff. Channel Firebats for a longer period of time to reach the maximum damage of Cloud of Bats after 3 seconds before the Oculus Ring buff runs out after 7 seconds. If you are lucky enough to have the new Oculus Ring spawns under you, channel as long as you can survive. Else proceed by pulling, moving and casting Piranhas Piranhado again to repeat your damage rotation.


This build is a bit squishy and it is hard to add additional toughness buffs. For Hardcore, make sure to stack extra Vitality and always use the Spirit Vessel passive. Check out our dedicated Hardcore Survival Guide to learn more about how to succeed in this game mode!


GR Solo Push
Arachyr Firebats Solo Push

The Spirit of Arachyr Solo build takes the awesome monster grouping power of Piranhas Piranhado and combines it with the strong AoE attack of Firebats Cloud of Bats. With Grave Injustice this setup has tremendous Cooldown Reduction as well as Life and Mana recovery rates if the monster density is high and the kill speed is fast. Bane of the Stricken is mandatory to kill the Rift Guardian.

Keep up your Soul Harvest all times and use Spirit Walk to skip bad map layouts, dodge attacks and projectiles, and to regenerate Mana with Honored Guest. DoT up enemies with your Locust Swarm to ensure the damage reduction from Cloud of Insects and the damage buffs from Bakuli Jungle Wraps and Ring of Emptiness. Cast Piranhas Piranhado to group up enemies and start channeling Firebats. Keep pressing Spirit Walk to survive but never stop channeling until you want to move to keep up Taeguk and Cloud of Bats.

At lower Paragon (below 1,000) Piranhas can be replaced with Summon Zombie Dogs Leeching Beasts for insane recovery. Also feel free to change Confidence Ritual to Spirit Vessel for better survivability.

Group Trash Killer
Arachyr Firebats Group Trash Killer

In this high Greater Rift focused setup we use full Area Damage and the insane Attack Speed from Pain Enhancer to deal tremendous amounts of AoE damage to enemies. Our zBarb enhances our damage by adding Health Globes with Threatening Shout Grim Harvest and creating pixelpulls with Ground Stomp Wrenching Smash.

Keep up Soul Harvest and Spirit Walk to survive and move through enemies unhindered. DoT up emeries with Locust Swarm and Haunt to get all your damage multipliers up and and regenerate Mana from Draining Spirit. Position yourself with Spirit Walk next to your Supports in dense monster pulls, cast Piranhas and start channeling Firebats. It is important to keep channeling Firebats until your group wants to move again. Do not let go off Firebats before that or else you lose your Attack Speed snapshot (further explained in the mechanics section below). Pray to RNGesus to get an Oculus Ring spawn right under you to increase your damage even further!

Without zMonk in the party, you cannot keep up Squirt's Necklace, which is why we go for Captain Crimson's Trimmings. At higher Paragon, you can replace Endless Walk with Squirt's Necklace and Convention of Elements. On the Passives feel free to change Swampland Attunement to Spirit Vessel if you prefer playing with a Cheat Death.

Echoing Nightmare
Echoing Nightmare Setup

For more information, check out our full Echoing Nightmare Guide and take a look at our Echoing Nightmare Build Tier List and our META post for the best builds and strategies! This build is bad for this game mode. Typically we utilize a Greater Rift pushing build with a few tweaks.


  • Drop Horrify for Big Bad Voodoo to increase damage.
  • Replace Piranhado with Wave of Mutilation to increase the range at which you apply the damage debuff.
  • Swap Bane of the Stricken for Pain Enhancer since we are fighting hordes of enemies.


  1. Click Speed Pylon instantly to boost your mobility and dodge Green Meteors.
  2. Around Wave 90, click Channeling Pylon and Power Pylon.
  3. After Wave 100, use Conduit Pylon.
  4. At Wave 122, stop attacking and run to the corner to let the timer run out.

We have awesome Big Bad Voodoo and Spirit Walk uptime as we are constantly killing enemies with Grave Injustice. Cast your Locust Swarm to DoT monsters. Always cast Soul Harvest when you are in close combat and the skill is off cooldown. Since Firebats has a 3 seconds damage and AoE ramp up, try to stand still and channel as much as possible. Stand on the Spider Queen's Web to get the Spirit of Arachyr (4) Bonus toughness buff. Use Spirit Walk wisely to damage burst with Shukrani's Triumph.

S7 Arachyr Firebats GR115 World #2 4man Action (zMonk PoV)


Firebats Cloud of Bats

  • Has a range of 15 yards around the Witch Doctor.
  • Has a ramp up time of 3 seconds to reach the full potential of 850% weapon damage.
  • Has an Attack Speed Coefficient of 2.0. The highest possible Breakpoint (3 Frames Per Attack) is achieved at 3.7501 sheet APS with Staff of Chiroptera at 47 Pain Enhancer stacks in this setup.
  • Attack Speed is snapshotted at the start of the channel, which means that if you start channeling a 3 FPA Firebats, it will continue attacking at that increased rate as long as you don't stop channeling.

Staff of Chiroptera

  • Gives Firebats a 150% separate damage multiplier which equals a 2.5 multiplier.
  • Halves Firebats Frames per Attack (FPA) but does not affect its mana cost. Firebats mana cost per tick is calculated this way:
  • Firebats base mana cost is 125 and its Attack Speed Coefficient is 2.0. In our situation, we have 10% Resource Cost Reduction (RCR), and benefit from the 75% less mana cost (Resource Coefficient) from Staff of Chiroptera.
    This mana cost per tick is then multiplied by our APS Breakpoint (without taking Staff of Chiroptera in consideration) to get the total mana channeling cost per second. For instance when the 3 FPA Breakpoint is reached, our mana cost will be 120.54 mana per second:

Shukrani's Triumph

  • The 100% Damage bonus while in the Spirit Realm from Shukrani's Triumph is an additive damage buff, meaning its effect is additive with other buffs such as Pierce the Veil.
  • You are in the Spirit Realm when in Spirit Walk and when Spirit Vessel procs.
  • After the initial duration of Spirit Walk (2 seconds or 3 with Jaunt), you stay indefinitely under Spirit Walk until you attack 3 times or until you have any Elite enemy within 20 yards.
  • A very interesting property of Spirit Walk is that you do not generate aggro under this effect, which means you are invisible to all monsters. This mechanic can be used at your advantage on some Rift Guardians which need a target to perform some abilities (Bloodmaw's Jump for instance).

Locust Swarm

  • When applied, Locust Swarm jumps to another nearby enemy once every second. With Creeping Death, this effect stays permanently as long as you are in range. It fades when you move ~1.5 screens away.
  • The Cloud of Insects rune can be used to apply bleed to enemies for Pain Enhancer, as any Physical DoT effect provides the extra Attack Speed effect.

Piranhas Piranhado

  • This ability is one of the few ways in the game to pixelpull enemies.
  • If used on top of enemies, it pulls them close together but does not pixelpull most of them. In order to get the best pull possible, it has to be used on a spot with no other nearby enemies.

Gruesome Feast

  • Each stack, received upon picking up a Health Globe, has its own duration.
  • You need 5 globes every 15 seconds or one Health Globe every three seconds to keep it at full power.
  • The Intelligence bonus stacks additively with Soul Harvest's bonus.


  • Put together the core items and acquire the full Spirit of Arachyr set.
    Iconic and fun playstyle with Firebats.
  • Scales with Area Damage and can snapshot Attack Speed.
  • Lightning fast channeling ticks but cause of many server issues & lags (the DoT effect of Spirit of Arachyr (2) Bonus adds even more strain on servers).
  • DoT enemies up as much as possible and keep up Soul Harvest at all time.
  • Fire away!

Cheers everyone!
