Aura

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 aura. Player A will gain a bonus on the energy shield granted by the aura. But party member Player B who is standing inside the aura radius of Player A will only receive the base amount of energy shield granted by the aura unless Player B also has energy shield boosting passives.

Sources

Most auras originate from skill gems. These can either be regular aura skills or curse auras.

Curse auras

See also: curse

With the use of the support gem, any curse gem may be converted into an aura. Curse auras are affected by both curse and aura radius increases. Most aura effect increases specify that they only apply to non-curse auras. They will have no effect on curse auras.

Curses applied via Blasphemy count towards the active curse limit.

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:

- This will cause linked auras to reserve health instead of mana.
- 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.
- Reduces the mana reserved by the aura.
- Adds levels to supported auras.
Note! - does not affect mana/health reservation.

Passive skills

There are passive skills that grant aura bonuses.

Area of effect radius for auras

These passive skills grant increased area of effect radius for auras.

Effectiveness of auras

These passive skills grant increased effect magnitude for 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
  Sinner TricorneEvasion: (664-850)Requires Level 64, 138 Dex+2 to Level of Socketed Aura Gems

  You have no Life Regeneration

Examples of this calculation are as follows.

4% reduced Mana Reserved, and Discipline:
ceiling(floor(50%)*(100%-4%)) = ceiling(floor(50%)*96%) = ceiling(49%*96%) = ceiling(48%) = 48%

Mortal Conviction, 6% reduced Mana Reserved, Prism GuardianPrism Guardian
Archon Kite ShieldChance to Block: 22%
Armour: (156-179)
Energy Shield: (32-37)
Movement Speed: -3%Requires Level 68, 85 Str, 85 Int+12% to all Elemental Resistances+2 to Level of Socketed Aura Gems
Socketed Gems Cost and Reserve Life instead of Mana
Socketed Gems have 30% increased Reservation Efficiency
+(20-30) to Dexterity
+25% to all Elemental ResistancesWhen blood is paid, the weak think twice., and Discipline:
ceiling(ceiling(floor(50%)*(100%-50%))*(100%-(6%+25%))) = ceiling(ceiling(floor(50%)*50%)*69%) = ceiling(ceiling(50%*50%)*69%) = ceiling(ceiling(25%)*69%) = ceiling(25%*69%) = ceiling(17.25%) = 18%

Or, in the most extreme case, Mortal Conviction, 38% reduced Mana Reserved, Alpha's HowlAlpha's Howl
