I have yet to see Twilight Devastation show up in my details or my actual combat log. I am a beast mastery hunter. I have even tried to stand in melee range of all the mobs I kill since the range is supposedly limited. I have 2 pieces with it, and I have tried it with just my boots, just my gloves, and the boots and gloves together. I know my regular corruption effects are working because I’ve gotten void ritual to proc. This issue has been happening for multiple days.
