Aura

An aura is a permanent effect focused on your character that also affects nearby party members and minions. Auras reserve a portion of your mana pool. Some skills reserve a straight amount while others reserve a percentage of your max. The 9 original auras were added in patch 0.9.7, and one additional () was added in patch 0.9.8.

All allies within range of a player's aura skill will receive an aura 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.

Support Gem Combinations

Auras themselves do not do damage. They provide a buff which can add extra damage. 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.

- Increases the radius of the aura.

- Reduces the mana or health reserved to maintain the aura. This works for both flat amount reservation and percent based reservation.

- Casts a totem which will maintain an 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.

Passives

There are passive skill nodes that grant bonuses to auras.

Note that "Reduced Mana Reservation" is multiplicative for both % and flat mana auras and the bonus is multiplicative with the Support Gem, the latter occuring first.

The "Increased Buff Effects on You" passive cluster near the Witch starting area also increases the effect of auras.
