Celtic Heroes

i want to know if its possible to kill so we can try a 2nd attempt or if its not possible to kill then why have it introduced

Is there anything that makes you think that it can't be killed now? It's died successfully at least 6-7 times since release, though I don't think it's died for a week or more.

Keep in mind that it's designed as a cross server boss - many servers are supposed to bring a lot of their best players in order to defeat it - if 1-3 servers were able to kill it, then I feel like there'd be a bit of a problem.
