local buffs, i = { }, 1;
local buff = UnitBuff("player", i);
while buff do
  buffs[#buffs + 1] = buff;
  i = i + 1;
  buff = UnitBuff("player", i);
if #buffs < 1 then
  buffs = "You have no buffs";
  buffs[1] = "You're buffed with: "..buffs[1];
  buffs = table.concat(buffs, ", ");
Macro Options:[edit]

1. Prints the names of all buffs on the current target:

/run for i=1,40 do local B=UnitBuff("target",i); if B then print(i.."="..B) end end

2. Prints the name, icon texture, and time left for all buffs on the player.

/run for i=1,40 do local n,_,icon,_,_,dur,x,_,_=UnitBuff("player",i);if n then print(i.."="..n..", "..icon..", "..format("%.2f",-1*(GetTime()-x)/60).." minutes left.")end end


  • Patch 1.9 added castable to the list of parameters.
  • Patch 2.0 added name and rank return values.
  • Patch 2.1 added duration and timeLeft return values.
  • Patch 2.3.2 changed behaviour of castable parameter - spells cast by other players are no longer shown at all when castable is used. Bug or intented change?
  • Patch 2.4 (PTR 8089-enGB) changed (again) behaviour of castable parameter - spells cast by other classes are no longer shown at all when castable is used. Tested with druid and priest spells, MacOSX client. Needs to be confirmed.
  • Patch 2.4 (Live) has corrected the bug introduced in 2.3.2. The castable parameter correctly filters non-castable buffs once again.
  • Patch 3.0 updated the return values.
  • Patch 3.1 changed the boolean return value isMine to the string value source.
