Have a sticky situation just tried to trio the event, 13k unbuffed beastlord, 10/10k cleric and rogue with decent gear, so i managed to finish the terror event, but was killed by DDA and his proc which kept flinging me into mobs and wiping me, so got back rebuffed and attempted again, managed to get rogue and cleric camped, but when got back DDA despawned, so question is what do i do next, do i have to do whole event again including bazu terror, already looted the dust from him

If you've got the Feral Dust, I'd go back to Muada and see what happens. I believe turning in the other drop is optional if you already know what to do. But if it doesn't work, you haven't really lost anything...you'll get another dust when you redo the event.
