   Wretched Vapors

   • Cooldown 40s
   • Cast Range 13m
   • Duration 4s
   • Cast Delay 0.2s

   Crack open a vial to release an ethereal vapor onto yourself or an ally that causes a rush, then a crash. Specter Rush: While it lasts, increases the speed of all actions and temporarily numbs all incoming damage creating looming specters. Specter Crash: When the vapors wear off, all actions are slower and any remaining specters deal their delayed damage plus extra damage. Incoming healing will prioritize removing specters first, preventing them from dealing damage.
