Well still not success on leave after Boss kill. But about to test a module I found on another post, which should gotoLabel(Leavehunt), but also sound an alarm after each kill =]
Trial and error number: who knows

Lua Code:
Code:
--    Leave after Boss --
 
Module.New("Fire Alarm", function(mod)
    if Self.isBurning() then
        gotoLabel(Leavehunt)
        mod:Delay(6000)
    end
end)


Thanks to @krille09 & @Kezzar I may have found a solution..
