Chaos DoT Occultist PoB, Passive Skill Tree & Gem Links




The PoB community fork created by Localidentity is the only version being kept up to date, so make sure you have the correct version: PoB Community Fork.


This build is extremely straightforward tree-wise. Budget-friendly versions include 0 Cluster Jewels, due to how volatile they are in terms of crafting difficulty and due to how expensive they can be.

Here is the Chaos DoT Low Budget PoB, and for a quick glance over the finished skill tree for this version, check out this link.

Once the skill-tree is finished, just focus entire on more jewel sockets or cluster jewels if you can afford it.


In the main page of this build guide you can see the detailed leveling progression up to the point of you reaching maps and will then switch to self-casting Essence Drain and Bane or Contagion.


A lot of the masteries available comes down to a matter of personal preference but some are more or less mandatory.

Life Mastery: “+50 to maximum life” this node is the strongest life mastery node so pick this up as soon as you can
Life Mastery: “Vitality has 100% increased mana reservation efficiency” this will help us reserve a stronger Vitality aura to help mitigate DoT dmg taken that the recoup and Petrified Blood doesn’t mitigate
Life Mastery: “10% increased maximum life & 10% reduced life recovery rate” a generic increase to our life pool
Chaos Mastery: “20% increased effect of wither” The absolute best chaos mastery notable available
Chaos Mastery: “1% to chaos damage over time multiplier per 4 chaos resistance” this is an easy way to get more DoT multi for our chaos damage but requires investing in to actual chaos resistances which isn’t a bad thing
Reservation Mastery: “15% increased mana reservation efficiency of skills” to allow us to reserve all the auras we need to make the build function this node is crucial to pick up
Resistance and Ailment Protection Mastery: “Corrupted Blood cannot be inflicted on you” ultimately this is a big Quality of Life node and shouldn’t be bothered with till you’re in later maps


There’s really only 1 proper node to anoint for this build and that’s Acrimony which requires: 1x Clear Oil Clear Oil & 2x Black Oil Black Oil.


6-Link Essence Drain

These links are strictly designed to increase the Damage over Time component of the skill in the best way possible:

  1. Essence Drain Essence Drain
  2. Void Manipulation Support Void Manipulation Support
  3. Swift Affliction Support Swift Affliction Support
  4. Controlled Destruction Support Controlled Destruction Support
  5. Efficacy Support Efficacy Support
  6. Empower Support Empower Support (The higher level the better, you could use a Decay Support Decay Support till you get a lvl 2-3 Empower)

3-Link Mobility

Generic mobility set-up with a curse mixed in:

  1. Flame Dash Flame Dash
  2. Arcane Surge Support Arcane Surge Support (Don’t level this above lvl 6 to make sure the Flame Dash triggers it on every cast)
  3. Enfeeble Enfeeble

3-Link Contagion

Contagion is the bread & butter for the “ED/C” build, you could use Bane Bane to apply a curse with in a 4-Link set-up but that’s a different playstyle compared to this guide, so the gems we use for Contagion are the following:

  1. Contagion Contagion
  2. Faster Casting Support Faster Casting Support
  3. Increased Area of Effect Support Increased Area of Effect Support

If you were to run a Bane set-up you’d need to switch around some of the gem set-ups described in this guide and look to apply your curse via Bane this way:

  1. Bane Bane
  2. Despair Despair
  3. Efficacy Support Efficacy Support
  4. Controlled Destruction Support Controlled Destruction Support

4-Link Wither Totem

Effective set-up to apply Withered on enemies which makes them take increased chaos damage:

  1. Wither Wither
  2. Spell Totem Support Spell Totem Support
  3. Multiple Totems Support Multiple Totems Support
  4. Faster Casting Support Faster Casting Support

2-Link / 2-Link Auras

We’ll be using an aura on our life pool since Petrified Blood drops our HP down by 50% we might as well make use of the upper half of that pool or it would be wasted! We also smack in a Withering Step set-up here:

Arrogance Aura

  1. Arrogance Support Arrogance Support
  2. Arctic Armour Arctic Armour

Withering Step

  1. Withering Step Withering Step
  2. Increased Duration Support Increased Duration Support

4-Link Auras & Golem

Mana reserved auras & our Stone golem fits here to help us sustain life regeneration:

  1. Vitality Vitality
  2. Summon Stone Golem Summon Stone Golem
  3. Malevolence Malevolence
  4. Petrified Blood Petrified Blood

    My favorite build in the game. Great guide Ghazzy!

    Hi Ghazzy,
    greatly described build! It’s my first DoT char and its going great so far.
    I’m planning on buying the 6L-Bow you mentioned, what would be a good gem setup for the second 6L then?


  3. GhazzyTV




    Hey, the links would remain the same but the bow would provide a significant damage boost through higher level gems :)
    Glad you like it sir!

    Hi Ghazzy,
    got that bow and quite a nice dmg boost. I just did my first attempt to kill Sirius on A5. Went ok until last phase. Every attack of him insta killed me.

    If possible can you have a look at my equip and give me a tip what upgrade would be best? Has to be something around 2-3 ex max. If I’m asking too much no problem!

    character name is EchoOfTheAssless

    This is a really NOOB question (and I have searched for the answer) but how do you get the mechanic of the synergy between Essence Drain and either the Bane or the Contagion to work?

    I feel like I’m constantly mis-timing when to cast each one.

  6. Posts

    Hey Rochambeaux,
    what Level are you currently? It felt the same for me at beginning. When mob packs got bigger it started to work.

    Just cast contagion on a pack and after that one or two shots essence drain. As soon as you hit a mob with ED that is inflicted by contagion it spreads through the mob pack.

    Also I found it useful to equip something with „projectile pierces enemy’s“ that way it’s easier to hit multiple mobs – and more than one to start the spredding.

  7. GhazzyTV



    Effman, Rochambeaux:

    Pierce or more projectiles can make it a bit smoother but with less DPS output sure. Contagion is the ability used to spread Essence Drain, if one doesn’t like to play that approach then we use Bane instead and use Essence Drain only for single target.

    Regarding your dmg output. There are a few ways to increase your dmg from where you are right now:

    1) +1 skill amulet (chaos or intelligence or both)
    2) -9% chaos resistance to nearby enemies (hunter influenced) helmet
    3) 21 ED

    I’m about to go live, feel free to come in to my discord server: and post in the #build-review chat channel and either myself or other veterans in my community will help you as soon as we can :)

    Hi Ghazzy,
    Couldn’t make it to your stream to ask my question..
    Does pierce lower the dps? And if so, why?

    thanks a lot so far!

  9. GhazzyTV




    Pierce would have to replace a support gem actually providing damage unless of course you have it on a modifier on any of your items (hunter amulet is a great example).

    Hi Ghazzy, thanks for the great guide! If I can though, I’d like to point out in the leveling section that using Bane with Spellslinger won’t work well. GGG_Mark stated that any spell linked by two triggers is completely disabled. This includes the Despair linked with Bane. I’ve used Soulrend (as you mentioned) and ED on Spellslinger with your bane setup on a self cast for bossing. But other than that this is great! I just started over Ritual in SSF and can’t wait to see how far I can get with the build.

  11. GhazzyTV




    My pleasure man, I’m just happy people enjoy my content!

    That’s odd, (regarding Bane on SS), I didn’t notice any issues with it, perhaps I need to dig in to this further, do you have a link to Marks statement on it that I could use as a reference when improving the guide?

    Hi @GhazzyTV

    Thanks a lot for the work you’ve done around this guide. Awesome build, clear, well-structured, and super effective.

    I’ve just finished the main arc story in 3 days with Lev74, ED deals 10k dps and 50k dot per second, just wow, never saw that kind of sick numbers in POE)) I start wondering how to improve my gear to scale in even more filthy numbers, do you have any guides for the end game activities?

    Though I didn’t get Empower Support yet, using Essence Drain+Void Manipulation Support+Swift Affliction Support
    Controlled Destruction Support+Efficacy Support+Decay Support GGBBBB in Tabula Rasa works really fantastic. You mentioned that the best chest will be max evasion, and in this guide, you have GGGGGG sockets body. But how I could get GGBBBB with max evasion? Is there any tricky way to put any color gems in the sockets?

    Another question with the 6-linked bow (alternative to wands) What skill to put there? Contagion? But it works pretty well with 4 linked BBBB and I hardly can imagine the value of adding more support stones to it

  13. GhazzyTV




    Glad you like it so much sir!
    Regarding the color part on evasion base, it’s a bit expensive and is basically all about using the chromatic bench-craft to get multiple blue colors on an evasion based chest.

    For the bow we utilize modifiers that increases the level of the socketed gem, this is to scale the Essence Drain the best we can, contagion should never be bothered to be focused for in terms of damage output.

    Hello and sorry for a noob question: so, during leveling I’m supposed to use two separate spellslinger links: one would be spellslinger+bane+despair+support gems and second one spellslinger+soulrend+support gems? Thanks in advance for any reply!

  15. GhazzyTV




    Never apologize for asking questions!
    Yes correct 2 separate spellslinging abilities :)

    Hello @GhazzyTV I hope you’re doing well

    After 20 days of playing with this build still enjoying it – maps clear speed is amazing – having so much fun running through the falling monsters beyond the screen after good Contagion + ED. Though still capable of doing 15-16 tier red maps, start feeling glass floor for increasing damage and survivability. Now on the 92 lvl I have 430k dps on ED and 7,5 eHP with 50%/56% dodge chance and around 14k evasion. Could you give me some directions on how to improve even more… is CI could be considered a good option? (-44% chaos res looks miserable) Is it possible to scale more damage? Cluster jewels maybe? Any advice for the “gear of the dream” worth collecting exalted orbs for?

  17. GhazzyTV




    Doing better thanks, was recently feverish (no corona though)!

    Well, optimally you’ll want to get a a bow with stacked + level to your gem modifiers and yes CI can offer you high eHP for less skill-tree investment which makes including clusters very easy to scale damage even further. You might also want to look at going Low-Life if you’re looking for super optimizing both defence & damage output. It’s obviously more expensive but it’s an effective way to scale very high end-game numbers.

    I’m sorry for being very noobish – but how do you fit the “end game gems” you list into these items? You have a lot of blue sockets, but red gems for totems e.g.

    Please ELI5 sorry :)
