We don't use nights calming at all. We don't use the -onebillion haste ones - I will personally sometimes fire them manually during a long fight if i'm cranking out alliance and end up getting behind on endurance, but we don't use them automatically
There is nothing that is "only do this once a target" (outside of things like UseOpener, obviously) and secretblade we just use it as part of our attack - there is nothing special about it. this would of course check for stacking and such - but you can see here me using it again in combat.
jugular line requires dots being turned on
this is all from the same fight
