Tracking Hidden Tier Set Buffs

[left onyx]

Is it possible to track buffs applied by hidden auras some way?

The goal here is to track the timer of the effect#2, without manually syncing to it

    if event == "COMBAT_LOG_EVENT_UNFILTERED" and select(12, ...) == 405565 then
        print("Found It")
        print(GetTime())
    end

this was my current approach, but it doesn't seem to trigger at all
I had a filter for source and event type and other things first, but I tried to relax the conditions, but still nothing

if the aura is hidden there is no way to track the aura itself

you would have to track the effect of it, in this gaining stormkeeper and starting a timer from the first event
