Aura

A Marauder with five auras: Determination, Grace, Haste, Hatred and Purity of Elements.

Auras are persistent area of effect buffs or debuffs that surround a person or creature and grant their effects to allies or enemies within the aura's area. This mechanic is widely used throughout the game.

Mechanics

Being a subset of buff/debuff system, auras inherit all characteristics from them and are affected by buff modifiers. They can be temporary or permanent, positive or negative, and so on.

Sources of auras:

• skill gems
• ascendancy passives
• monster skills and modifiers
• elemental proliferation
• items, such as SingularitySingularity

Mana Reservation

See also: Mana reservation

The vast majority of Auras are cast by reserving mana to maintain their effects. Mana reservation sets aside a portion of mana as unusable for as long as the skill is active. Having mana reserved does not reduce the rate of mana regeneration, so it will reduce the time taken for mana to regenerate to its (temporary) maximum.

Reserved mana values are multiplied by support gem mana cost multipliers as usual. The Blood Magic passive will cause life to be reserved instead of mana. The gem does not reduce the mana reserved by an Aura. Passives and items that reduce mana reserved do so multiplicatively; having a combined 20% Reduced Mana reserved reduces the cost of Vitality from 35% Mana reserved to 28% Mana reserved, not 15%.

Player auras

All allies within the area of a player's aura skill will receive the aura's buff. The magnitude of that buff is determined by the Aura generator's Increased Effect of Auras stat. However, that stat has no effect on the strength of an Aura received from someone. Passive and item modifiers can further enhance the effects received from an aura.

For example, Player A is generating a Level 20 Discipline aura; granting everyone inside the aura 303 Energy Shield. Player A also has +25% Increased Effect of Non-Curse Auras, thereby increasing the amount of Energy Shield to 379. Player A has no increases to Energy Shield, so they will only see an increase of 379 Energy Shield. Player B has +100% Increased Maximum Energy Shield and stands inside Player A's aura, thus Player B sees an increase of 758 Energy Shield. Player B's own "Increased Effect of Auras" stat has no bearing on the effect of the Discipline received from Player A.

The passive tree can provide 69% aura effect which requires heavy point investment though. The Guardian Templar class can have an additional 10% effect and the Champion Duelist class an additional 5%. Conqueror's Potency can provide another 3% effect. Through the use of Victario's Influence with its lvl 30 Generosity Support and up to 15% increased effect mod, an additional 64% increased aura effect can be obtained. However, supported auras will not affect you. If the player equips a Dying Breath, an additional 18% effect can be achieved at the cost of a shield (such as Prism Guardian) and weapon (such as Advancing Fortress or Ephemeral Edge) All this sums up to a maximum effect of 154% for non Champion/Guardian, 159% for Champion and 164% for Guardian.

There is no limit to the number of Auras a player can cast, so long as they have the resources to maintain them.

Note: Tooltip values only show the base aura effects; they do not show modified aura effects.

Curse auras

See also: Curse

With the use of the gem, any curse gem may be converted into an aura, thereby reserving mana to maintain a persistent curse effect around the player. Enemies who enter the Blasphemy aura are then cursed with the supported curse skill(s). Blasphemy auras are affected by both Curse and Aura Area of Effect increases. Most Aura effect increases specify that they only apply to non-curse auras, so they will have no effect on curse auras. Curse effect increases will function normally on curse auras.

Reduced Mana reserved modifiers affect Blasphemy auras in the same way as other auras; likewise, Reduced mana cost has no effect on Blasphemy auras. All Blasphemy auras reserve the same base amount of mana: 35%.

Curses applied via Blasphemy count towards the active curse limit. Curse auras also take priority over curses applied via casting, and will override those curses if they exceed the curse limit.

Note: Tooltip values only show the base curse effects; they do not show modified curse effects.

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 support gems have no effect on linked Aura skills. These support gems will affect auras:

- 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.
- 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.
- Increases the effect of the non-curse auras on allies (including minions) but prevents them from affecting the player.
- Further increases the Area of Effect of the Aura, but increases the Mana reservation by the gem's multiplier.
- Reduces the mana reserved of the aura by the amount of the mana multiplier.
- Adds levels to supported auras, but increases their cost by the mana multiplier.
Note that does not affect reservation, but does affect auras supported by Spell Totem Support.
