Returns
- name

- count
- Number - number of times the aura has been applied to the target, or 0 for auras that do not stack

- Number - full duration of the aura in seconds
- expirationTime
- Number - time in seconds (comparable to GetTime()) when the aura will expire
- unitCaster
- String (unitId) - unit that applied the aura, or nil if no valid unit token currently represents the caster
- canStealOrPurge
- Boolean - true for buffs that can be stolen by mages with
[Spellsteal], or false for debuffs and for buffs that cannot be stolen, or for debuffs - nameplateShowPersonal
- Boolean - true for buffs that should be shown on player/pet/vehicle nameplates
- spellId
- Number - spell ID of the spell or effect that applied the aura
- canApplyAura
- Boolean - true for auras the player can apply (not necessarily if the player did apply the aura, just if the player can apply the aura)

- isCastByPlayer
- Boolean - true for auras applied by players
- nameplateShowAll
- Boolean - true for auras that should be shown on all nameplates

- ...
- Additional values pertinent to specific aura (HoTs, traps, amounts etc. For example, the first value for Vengeance is its attack power bonus.)
Examples
- UnitAura("target", 1)
- the first buff on the target
- UnitAura("target", 1, "PLAYER HARMFUL")
- the first debuff cast by the player on the target
The following macro prints the names of any stealable buffs on the current target, or a notice if nothing is stealable:
/run local y,n,s,_ for i=1,40 do n,_,_,_,_,_,_,s=UnitAura("target",i)if s then print(n.." on target, steal it!")y=1 end end if y~=1 then print("No stealable buffs.")end
Notes
- Spell ranks were removed in Patch 4.0 (Cataclysm), so the rank argument to this function is largely useless today.
- Some filters are mutually exclusive. Using "HELPFUL HARMFUL" together will return no results, since no aura can be both a buff and a debuff at the same time. Using "CANCELABLE NOT_CANCELABLE" will also return no results, since no buff can be both removable and unremovable.
- The debuffType return value is not localized.
- The UnitBuff function is an alias for using UnitAura with the "HELPFUL" filter. The UnitDebuff function is an alias for using UnitAura with the "HARMFUL" filter. Both aliases will ignore the "HELPFUL" and "HARMFUL" filters, but will accept other filters.
