We've seen 2 Savory Shanks off it also. Been spamming it for days to get the torque. Was an unexpected nice surprise for the ring. If you think its not legit you can see him wearing it on his character on AH as of today.
As much as I'd like to say Kenrusai's theory is correct. He/she isn't. The reason I know this is because I was there at the time killing KB (0/106 BTW). There is no way that they could have gotten the drop off the KB at the same time as their fight took nearly to the time limit (as well as the fact that we popped multiple KB/B in a row). So, good try. Now for the OMG YOU'RE LYING! HAX!!! RATE HIM DOWN!!!! onslaught.
If this is real, I wholly expect there to be loads of shouts for this UC full of people that have been jaded over not being able to get one over the years.
fake, they killed a king behemoth which dropped dring prior to opening a coffer, and passed the ring as he opened the coffer to make it appear as though it came from the coffer.
