Poison Concoction/Bladefall Blade Blast Occultist


Introduction

Welcome back to another great map blasting build. The Poisonous Concoction Occultist is the premier mapping focused character with its built in explosions from Profane Bloom. This allows chain explosions, which is an extremely satisfying mapping experience when combined with Plague Bearer. Later on in the build, you swap to Bladefall and Blade Blast for more damage and Life recovery from +# Life gained for each Enemy hit by your Spells.

Skills Breakdown

Poisonous Concoction

With your main hand empty, throw your Poisonous Concoction to cover your foes with an acrid mix of toxins. Overlap your projectiles to inflict many Poison stacks onto enemies, dealing Chaos Damage over time. Upgrade your weapon by turning the life recovery of your Divine Life Flasks into Chaos Damage causing massive damage, at little cost. Level and clear the atlas as Poisonous Concoction until you have enough gear to swap your main ability to Blade Blast.

Blade Blast

Unleash a torrent of blades with Bladefall to leave Lingering Blades surrounding your foes. Before they react, use Blade Blast to cause your Lingering Blades to explode dealing massive damage to anyone caught within their radius.

Utility And Auras

Activate your Auras giving you Evasion and Armour through Grace and Determination. Molten Shell activates a shield scaled with your Armour. Shield Charge is your main movement ability, causing you to slam your shield, face first, through enemies.

Despair

Despair is the main curse of our build and gives us gigantic explosion chains when you obtain a Despair On Hit Ring. This causes your Profane Bloom to also apply Despair. Your second curse Temporal Chains will bind your enemies movement (slowing them to a glacial pace) while your Poison inflicts its damage over a longer duration.

Totem

Ancestral Protector provides you with the speed of your ancestor, giving you more Attack Speed. Throw down this totem on strong enemies to inflict many more stacks of Poison.

Plague Bearer

You can incubate (store) your Poison inside of you with Plague Bearer. While incubating for use later, you deal less Poison damage. Activate your Plague Bearer when full to unleash a Chaos Damage cloud around you. While releasing your Plague, run through packs of monsters and let your Profane Bloom wreak havoc among their ranks.


Ascendancy Breakdown

Occultist Ascendancy Breakdown

The Occultist is the best choice for Poisonous Concoction as it provides explosions to clear packs, an additional curse and damage to take care of Map Bosses, and an additional Wither application method for even more damage.


  • Profane Bloom causes your curses to consume the corpse of your enemies, triggering a cascade of explosions once one has fallen.
  • Void Beacon gives nearby enemies -20% to Chaos Resistance and prevents them from regenerating Life.
  • Withering Presence applies Wither stacks to nearby enemies, gives you +60% to Chaos Resistance, and makes your Chaos Damage 15% more potent.
  • Malediction allows you to inflict an additional Curse on enemies and causes those cursed enemies to have the Malediction debuff. This debuff causes 10% increased Damage Taken and 10% reduced Damage Dealt.

Playstyle

Level as Poisonous Concoction through the atlas by simply throwing your vials onto your enemies to inflict Poison. After you obtain enough gear, swap to the BF/BB setup. Lay down your blades with Bladefall and explode them with Blade Blast. On both versions, incubate your Poisons with Plague Bearer and unleash them when full.

Mapping

Focus on using your main damaging ability until you're at Maximum Plague Value. Unleash your Plague Bearer and Shield Charge through packs of monsters, letting your Profane Bloom take care of everything until your Plague Value is empty. Simply repeat the process for fast clear.

Bossing

Bosses don't go down easy, so save your Plague Bearer to use on the Map Boss. Put down your Ancestral Protector when playing Poisonous Concoction, and use Focus, giving you Ailment duration. Apply your Curses and unleash your Plague Bearer.


Build Scaling

Offence

Poisonous Concoction Occultist is a Chaos Damage over Time Poison Attack build scaling with:

  • #% increased Amount Recovered rolled onto a Divine Life Flask. Upgrading your Life Flasks gives you damage, so do it often while leveling!
  • #% Increased Chaos Damage
  • #% Increased Attack Speed
  • Despair and Temporal Chains to increase and extend Poison Damage.
  • Accuracy to obtain 100% hit chance.
  • #% chance to Poison Enemies on Hit
  • #% increased Damage over Time
  • #% increased Poison Damage/Duration
  • +x% to Chaos Damage over Time Multiplier
  • #% increased Area of Effect causing Multiple Projectile overlaps

Once you make the swap to BF/BB (Bladefall + Blade Blast) you will no longer scale #% Increased Attack Speed or Accuracy, instead you scale #% Increased Cast Speed and Gain #% of Physical Damage as Extra Chaos Damage.

Defence

The Occultist's lack of good recovery is one of the main reasons to swap to BF/BB (Bladefall + Blade Blast). Your mitigation and avoidance is plenty for mapping.

  • Armour from Determination and Granite Flask combined with Molten Shell provides a large shield.
  • +18 Life gained for each Enemy hit by your Spells (When playing BF/BB)
  • 100% Spell Suppression
  • Freeze Immunity
  • Reflect Immunity
  • 10% reduced Damage taken from Malediction
  • 20k Evasion Rating giving 70% Evade Chance.
  • 20k Armour giving us a moderate protection against Physical Damage.
  • % of Physical damage from Hits taken as Fire damage
  • 3 Endurance Charges granting 12% Physical damage reduction total.

These defences preform well in Maps with some Evasion Rating giving enough avoidance against attacks. Your Armour combined with Endurance Charges and Physical damage from Hits taken as Fire mods provide enough Physical Mitigation. .

Key Leveling Notes

Warning: This build is difficult and slow to level. If you are a beginner player, it is recommended to play the Poisonous Concoction Pathfinder. The Occultist version eventually has better clear due to Profane Bloom, at the cost of leveling slower and coming online later.

This build will level as Holy Flame Totem and Flame Wall, and will do Library in Act 3 to gain access to Poisonous Concoction. You will use this to level until you gain the cast speed in late game necessary to swap to BFBB.

The "Wand Craft" is the easiest way to make any caster leveling better. Selling a magic wand, an Orb of Alteration, and a normal Topaz Ring produces a wand like this: Snapping Driftwood Wand.

If you need a magic wand, purchase a 3-linked wand from Nessa with favorable colors, those being Blue-Blue-Green, Blue-Blue-Blue, or Blue-Green-Red. Then use an Orb of Transmutation on it. If you need a Topaz Ring, you can sell an Iron Ring with any Skill Gem that is colored Green.

Note: Selling rare items identified they will give you Alteration Shards, while selling them unidentified gives Transmutation Shards.

Campaign Step By Step

Beginner players should follow Enki's Campaign Progression guide.

The levels listed below are based on speedrunning. Always be greater or equal to the levels listed.

Use slider for progression.
Open Poisonous Concoction Tree in new tab and use arrows at the bottom to navigate.


Mapping Preparation

You're done with the Campaign and ready to take on the Path of Exile Endgame. Priority 1 is to ensure your Elemental Resistances are capped (75%) and have sufficient Attributes to continue leveling your Skill Gems. Use Essences you have gathered on any item that is not Magic or Rare already. Items with an open modifier slot should be crafted on. Go to the Crafting Bench and craft Resistances wherever possible according to what you need, and Life wherever else possible.

On league start, Heisting and doing the Chaos Orb recipe is a great and easy way to obtain currency. From this point on, grind your Atlas out by progressing and completing Maps.

IMPORTANT! Upgrade your flasks to Divine Life Flask when you hit maps and roll them for #% increased Amount Recovered as this is your "Weapon" when using Poisonous Concoction.

Map Modifiers

Take note of the below modifiers, as they should be avoided if they appear on your maps:

  • Less Armour reduces your main defences.
  • Reduced Effect Of Auras eliminate our defences.
  • Cannot Leech removes how we regain our Mana.
  • -X% maximum Player Resistances causes you to take extra Elemental damage.

First step is to progress through the Atlas following our Atlas Progression Guide. As a mapping focused character, you should focus on gearing your character with strong pieces to prepare yourself to farm Red Map content. If you're struggling in higher tier content, go back and farm up more Currency and Gear. The endgame section below will take you to detailed Farming Guides based around maximizing your profits.


Pantheon

For information about the Pantheon and how it works, consult our Pantheon Guide!

For Major Pantheon, select Brine King to gain Immunity to Freeze and Reduction of Chill Effects. This bonus is not available at first. It’s acquired with Divine Vessel.

For Minor Pantheon, select Garukhan and upgrade it. This grants reduced Effect of Shock, preventing large damage spikes, and Cannot be Blinded (to prevent a loss of Accuracy).


Skill Gems

Gems are a fundamental part of your build. Getting the correct link setups before entering Maps and leveling those Gems as you progress through the Atlas is one of your main goals.

If you don't have enough Sockets, simply remove the Lifetap Support and Increased Area of Effect Support from the Withering Step/Plague Bearer setup. If you need to remove more, drop the Lifetap Support from your Shield Charge as well. Keep in mind, removing Shield Charge will make your Mana strained. So try to re-add these when you get enough sockets!

Use Slider to see Skill Gems Progression

Poisonous Concoction Setup

Poisonous Concoction is your main ability until the BF/BB swap. This skill gem can hit multiple targets with its overlapping AOE projectiles, so link Greater Multiple Projectiles Support and Greater Volley Support. Void Manipulation Support provides raw damage, with Unbound Ailments Support providing additional damage and duration of ailments. The last link will be Lifetap Support to ease our early Mana issues by not being forced into a Mana flask.

Movement

Your primary movement ability will be Shield Charge linked to Faster Attacks Support. Use Flame Dash to traverse over gaps and make sure to link Lifetap Support to this entire setup to ease your Mana pressure.

Ancestral Totem

Ancestral Protector is put down for tough enemies. Use this before starting a boss fight, as it provides more Attack Speed. Once you swap to BF/BB, don't use this anymore.

Auras

Use Determination to mitigate Physical Damage. Use Grace to obtain Evasion Rating, giving you Chance to Evade Attacks. When you have enough Vaal Orbs, corrupt your Grace into a Vaal Grace. Use it right before engaging with a boss for a huge boost in Chance to Evade Attacks. After the BF/BB swap, use Defiance Banner to boost both Evasion Rating and Armour.

Plague Bearer + Withering Step

Link Plague Bearer and Withering Step to Increased Area of Effect Support to make them affect a greater amount of monsters. Plague Bearer should be treated as your main clear ability that you load up and release onto monsters. Withering Step is how you apply the Wither debuff, causing enemies to take 6% increased Chaos Damage per Wither.

Blasphemy Temporal Chains

Blasphemy Support linked with Temporal Chains makes your Curse into and Area of effect Aura. This allows you to easily Curse enemies who come within that area. This pairs very well with Profane Bloom giving you easy explosions. Temporal Chains is chosen because it makes effects on enemies expire slower. This means our Poison does the same amount of damage per second, but does more damage in total. It also causes enemies to become slower, which stops enemies from hitting you and helps you recover damage taken in between enemy attacks.

Cast when Damage Taken

Cast when Damage Taken Support should be linked to Molten Shell to trigger a protective shield that scales off Armour and absorbs damage for a duration. If you can't use Determination to scale your Armour yet, then replace it with Steelskin.

Bladefall Blade Blast (BF/BB)

Once you obtain everything needed to preform the BF/BB swap, change your main ability to Blade Blast and Bladefall. This one-two combo will provide you with some much needed Life Recovery and some additional damage. Link Blade Blast to Chance to Poison Support for flat Chaos Damage and Chance to Poison, Increased Area of Effect Support to increase the explosion radius to cause overlaps and then Void Manipulation Support, Unbound Ailments Support and Deadly Ailments Support for pure damage.

For your Bladefall, link a Level 1 Unleash Support to cause repeats of this ability, leaving the maximum amount of lingering blades on the ground. Use a Level 1 Spell Cascade Support to cause a repeat of this ability in front and behind where you targeted, helping leave even more lingering blades. Lastly, Link Concentrated Effect Support to cause your lingering blades to fall within a concentrated area, allowing more overlapping explosions from Blade Blast.

NEW BOSSING SETUP

For Pinnacle Bosses, you should replace Unleash Support with Arcanist Brand, and follow the recommended passive tree in the End Game POB. This will have you take Runebinder which allows you to have 2 Brands attached to enemies. Then you simply spam Blade Blast after your Brands cast Bladefall.

Bladefall Blade Blast (BF/BB) Swap

Swap to BF/BB after leveling with Poisonous Concoction to level 88. You are swapping at this point because BF/BB does more damage and has a better recovery method through the use of +# Life gained for each Enemy hit by your Spells. The stat you need on your gear to make a comfortable swap is increased Cast Speed on your Wand, Ring, Amulet, and Gloves. This may sound intimidating, but with Harvest Reforge Caster, it becomes trivial. You will need an 8 passive Large Physical Cluster, a 5 passive Chaos Damage over Time Medium Cluster, a 5 passive Critical Strike Chance Medium Cluster, a 2 passive Enduring Composure Armour Small Cluster, and a 2 passive Mana reservation efficiency Small Cluster. These bases are all easy to purchase or craft. They are also covered at the end of the Early Game Milestones.
