Yah I had the doubled edge sword with one fate in Coerthas, giant saps, was waiting ages no spawn, so went off to kill other spawns, it popped and died before I could get to it, asked in shout when I saw it spawn, that if anyone doing it please don't go all out and wait a minute.
With a response "suck it up and next time learn to camp" ofc was long dead by time I got there and I wasn't even that far away
