It's like rdonj says. Each set of hitpoints is associated with one of the heads. It's something like 70hp to chop the first head off, another 70hp to chop the second head off, and finally 80hp to chop off the final head. Those probably aren't the actual values any more.

As for the Ember Lord, there was a version of CBM where he had lost flying. Maybe there is a client/server mod version mismatch, where your copy of the mod thinks the Ember Lord can fly but the server doesn't. What exact mod filename are you using in the problem game?
