Drops from Yilbegan VNM tier 4 NM. This NM was added in more zones during the june 21st,2010 update. Lucky coin was added to its drop list with the june update.
Credit goes to the ppl on BG who killed it and provided a screenshot.

The person filming that clip has shadows effects switched off, can tell because not even the players have a shadow. It would take some TH to even get 1 ring let alone 3 without shadow.
As said already by Zagarikano, drops from Yilbegan, however, unlike Yilbegan's Ring's, this does NOT require a shadow to be present, thus giving a reason (However slight) to actually fight the ***.
My puppet would kill me if I took off my animator to equip this...
Nice for the other jobs on it though. I'd go for the new attack option though, your acc will be capped on most things. If not, this is definitely an awesome piece!
