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
- 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.
debuffTypereturn 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.
