Vaal Impurity of Fire Quality

Per 1% Quality: 2% increased Area of Effect. Because a Gemcutter’s Prism Gemcutter’s Prism can’t be used on corrupted gems, getting quality on vaal gems is substantially harder than it is on a regular gem. Vaal gems must either drop with quality or a normal gem already with quality must have a Vaal Orb Vaal Orb used on it and be turned into a corrupted Vaal gem.

Vaal Impurity of Fire Support Gems Build

Vaal skills cannot be supported with Multistrike Multistrike Support, Ancestral Call Ancestral Call Support, and Spell Echo Spell Echo Support. These support gems will affect Vaal Impurity of Fire Vaal Impurity of Fire auras:

  • Blood Magic Blood Magic Support – This will cause linked auras to reserve health instead of mana, but increase the cost by the mana multiplier. Note that “reduced mana cost” from increases in quality have no effect on mana reservation.
  • Spell Totem Spell Totem Support – Casts a totem which will maintain the aura. The cost to cast the totem is the mana that would be reserved multiplied by the Mana Cost Multiplier of the Totem support and any other linked support gems.
  • Generosity Generosity Support – Increases the effect of the non-curse auras on allies (including minions) but prevents them from affecting the player.
  • Increased Area of Effect Increased Area of Effect Support – Further increases the Area of Effect of the Aura, but increases the Mana reservation by the gem’s multiplier.
  • Concentrated Effect Concentrated Effect Support – Lessens area of effect and applies the mana cost mulitplier, but does not provide a bonus to aura damage, as auras cannot directly cause damage. An exception would be the aura from Death’s Oath Death’s Oath.
  • Enlighten Enlighten Support – Reduces the mana reserved of the aura by the amount of the mana multiplier.
  • Empower Empower Support – Adds levels to supported auras, but increases their cost by the mana multiplier.
  • Enhance Enhance Support – Increases the quality of the gem, granting increased area of effect, but at increased mana cost.

Note that Inspiration Support does not affect reservation, but does affect auras supported by Spell Totem Spell Totem Support.
