Build Info & Scaling

Learn about the key build info and how to increase damage and defense with your stats and gear for the Poison Spark Occultist Build.

Build Scaling


Poison PhantasmalSpark Occultist is a Chaos Damage over Time Poison Spell build scaling with:

  • #% Increased Chaos Damage
  • #% Increased Damage
  • % increased Cast Speed
  • #% increased Damage over Time
  • #% chance to Poison Enemies on Hit
  • +# to Level of all Spell Skill Gems
  • +# to Level of all Lightning Spell Skill Gems
  • #% increased Poison Damage/Duration
  • #% to Chaos Damage over Time Multiplier
  • #% to Damage over Time Multiplier
  • Gain #% of Lightning Damage as Extra Chaos Damage
  • % increased Projectile Speed
  • % increased Skill Effect Duration
  • #% increased Effect of your Curses to scale Despair, Temporal Chains and Punishment.

The Poison PhantasmalSpark Occultist comes with more than enough defenses to take on all the Uber content in the game, these defenses include:

  • Determination and Granite Flask combined with Molten Shell provide a large shield
  • #% increased effect of Non-Curse Auras from your Skills, increasing the effect of the buffs granted by Grace and Determination
  • 100% Spell Suppression
  • Ailment Immunity
  • Reflect Immunity
  • Energy Shield
  • Mind Over Matter
  • Evasion Rating, giving you a chance to avoid incoming attack damage
  • Armour, giving you moderate protection against Physical Damage

The Main downside of the Occultist's defenses is its recovery. This is partially solved early on with a well rolled Life Flask, Life Gained on Kill and Life gained on hit granted by Watcher's Eye. Additionally Ghost Dance restores a huge chunk of your Energy Shield when hit.

Key Build Info

The PhantasmalSpark Poison Occultist relies on scaling gem quality to 50%. PhantasmalSpark alternate quality converts a portion of Spark's Lightning Damage into Chaos Damage, thus making it able to Poison. This is achieved thanks to the Ashes of the Stars Unique Amulet, which can roll up to 30% to Quality of all Skill Gems. It is essential for the build to get 30% on this roll as otherwise you will not have 100% of Lightning Damage Converted to Chaos, resulting in a massive loss of total damage. Poison damage also relies on Poison Chance to inflict it's damaging ailment. 100% Chance to Poison must be achieved by equipping a Divergent Herald of Agony which thankfully is also scaled by Ashes of the Stars.

Skill Mechanics

A single PhantasmalSpark can hit an enemy once every 0.66 seconds. Keep in mind this is per cast, not per projectile. Without any increase in duration, a single cast can hit an enemy thrice with the base duration of 2 seconds.  Spark projectiles bounce off of terrain obstructions and edges for as long as they persist. If a spark projectile strikes a mob, it is absorbed unless it can pierce. That is why projectile speed, increased duration and pierce can result in significant increases in real DPS.

Bandits: Kill all

For Major Pantheon, select Lunaris to gain additional damage reductions. Additional bonuses are not baseline and need to be acquired with a Divine Vessel.

For Minor Pantheon, select Tukohama and upgrade it. This grants you Physical Damage Reduction and Life Regeneration. Alternatively, you may want to select Ralakesh until you gain Corrupted Blood from a flask suffix or jewel corruption.
