I engaged a ravenous cragbeast, and all of a sudden hp's were going down fast. I noticed that a cragbeast bonecruncher was hitting me for up to 2504, and was an apparent add. Before I could do anything about it, I was dead. I realized later that the bone cruncher is the shape shifted form of Tqiv Trusik Fanatic, who had popped about ten minutes earlier after my previous sucessful encounter with him/her/it in spider form. Pop time was about two hours. Of note is that even though the name changed several times while I was tracking Tqiv Trusik Fanatic, it didn'nt change it's place on the normal tracking line up. Meaning it wasn't resapawning, just changing names and shapes. When I got rezzed, and had it on target, it changed names while staying my target.
