Does anyone know of any spell/song/ability that blocks or knocks off STC? Once on raids tonight I used it, got the 10 min re-use, but I didn't get the song, or the initial burst of endurance. Same thing happened with Breather once tonight, which has never happened to me before, so I wonder if it was just crazy server lag.
Most likely from having the effects of Blood Drinker's Coating on In regards to Breather it has an upkeep of 1 Endurance per Second, so if you were to say get Endurance drained to 0 (or perfectly use an ability/disc that takes you to exactly 0) then it attempts to use the 1 Endurance required for Upkeep you won't have it, thus it can and will poof
