Aura

From DotA Allstars Wiki

Auras

Auras are passive abilities which provide buffs that occur in a specific Area of Effect of a Hero or Neutral Creep.

Auras are normally positive effects which give the hero and nearby allies a boost,but at times can be negative and effect nearby enemies.

Stacking Auras

Auras are capable of stacking with each other regardless of being of the same ability as long as their internal names are different, with the exception of Devotion Aura-based abilities, due to an engine setting. Crystal Maiden's Brilliance Aura is no exception; it stacks with the Brilliance Aura of Ring of Basilius because internally, the buffs they place are different. The name and bufftip values are the same, as well as the icon, and visual effect, but the internal ID's used by the engine are different.
