Aura

From Path of Exile Wiki
Jump to: navigation, search
A Marauder with five auras: Determination, Grace, Haste, Hatred and Purity of Elements.

Auras are permanent buff effects that benefit the player and extend their benefits to nearby party members and minions. Regular auras (applied by skills) reserve a percentage of the player's mana pool, with the exception of Clarity, which reserves a flat amount.

All allies within range of a player's aura skill will receive the aura's buff. Passive and item mod bonuses can apply to the stats granted by auras, but these bonuses are determined by the passives and items of the receiver, not the player who is the source of the aura. For example, player A has passives for extra energy shield and is generating a Discipline inventory icon.pngDiscipline

Skills

Support Gem Combinations

Auras themselves do not do damage. They provide a buff which can add extra damage, extra defenses or utility. As with curses, added damage supports can't be linked with auras successfully. These support gems will affect auras:

Calculation Mechanics

The calculation to determine the reservation cost of an aura is ceiling(ceiling(floor(base Mana Reserved * Mana Multiplier) * (100% - less Mana Reserved)) * (100% - reduced Mana Reserved)).
With equipment and passives available as of version 1.3, each category includes the following.


  • Mana Multiplier: Support Gem.
  • Less Mana Reserved: Mortal Conviction.
  • Reduced Mana Reserved: All passive nodes which provide "reduced Mana Reserved", Alpha's HowlAlpha's Howl
