This weakaura identifies buffs you are missing that are specific to tanking twin emperors as a warlock. The weakaura loads only if you have Rank 7 gloves equipped and are in a raid (but the item used to load the weakaura can be modified in the "Load" tab). This way, the weakaura shows only once you switch into gear for tanking twins.
This weakaura is intended for use with the Warlock Missing Raid Buffs weakaura, https://wago.io/K1iGiyo5_ though it will work independently.
Buffs tracked include:
Greater Frost Protection Potion
Spirit of Zanza/Lung Juice Cocktail
Stamina Food
Stamina Alcohol
Elixir of Fortitude
Elixir of Greater Firepower
Gift of Arthas
