GM BLOG The Battle of Crimsonwood Keep

Before you get ahead of yourself wondering if bigger = stronger than HT, remember that we probably have to fight it with 6 people. Unless they release it like Zakum or HT with a sign up sheet... which I am REALLY hoping they don't.

Remember this, he says there will be multiple bosses, and tthe magazine article said multiple bosses at once as well. Its likely that the grandmasters are the bosses, maybe this is there too, but that'd be a LAGGGGY bossfight.
