Anyone know what Era this comes from? As of Shadows of Luclin it isn't searchable under /buyer so I assume it was added at a later time.
The entry for this item was 2006-12-19. Which means it was during The Serpent Spine expansion. Now that doesn't necessarily mean it was added to the game at that time. It just means someone finally updated the item via our item collector. The Hole was made a hot zone on the December 5th, 2006 patch. However comments on the mob that drops this item show the first comment was from January 2007 so I'm pretty sure this is a TSS item.
