UnitDebuff() + GetSpellInfo()

[pas06]

No problem, i hope it works as expected in every situation and i didn't forgot anything

Apologies, i now see the error in the code i posted in post #15, which for some reason hid from me.

i like the approach Pas has posted... Less if and function calls can only help.

although i would add [Ticker = -1], with out it, the loop won't stop.
You also don't need the [duration, expires] variables anymore

local function UNIT_AURA()
    if UnitDebuff("player", TaintOfTheSea) then
        if not debuffexists then
            debuffexists = true --player just got the debuff
            Ticker = 8
            UpdateTicker()
        end
    else
        Ticker = -1
        debuffexists = false -- doesn't exist
    end
end

I guess you missed the change in line 8 that i made. That's what causes the loop to stop.
