Retrieve who cast a buff on you with LUA custom code for Weak Auras

[Falaenx]

Goal: Weak Aura to track external Cooldown on me and print out in the text who the caster of the buff was

I have made the weak aura to track an external CD aka "Hand of Sacrifice" but I need custom code to retrieve the caster of the buff

I think I need to use this function

name, rank, icon, count, debuffType, duration, expirationTime, unitCaster, isStealable, 
shouldConsolidate, spellId = UnitBuff("unit", [index] or ["name", "rank"][, "filter"])

and retrieve the unitCaster return

But I am very novice with LUA code so any help would be greatly appreciated

Thankyou!

I would use COMBAT_LOG_EVENT_UNFILTERED to simplify things.

In the custom text field you put %c and then for the custom function use this

function()
    return UnitName((select(8,UnitBuff("player","Hand of Sacrifice"))or "")) or UNKNOWN
end

Thank you for the help

Here is a weakaura group that handles every external cooldown, displays duration and who cast it on you.
