This is just a friendly community reminder to the Bombers playing on 360 in the NA region the Ur Dragon is at one bubble and some life bar as of 6/20/2012 9:02 am EST. So if you are playing this version of the game, have time right now, and want an online Ur Dragon kill now would be the time to log on and get to it.
Currently all he has left is the middle and end piece of his tail, both front claws, the top half of his front left leg, the portion of his neck closest to his torso, and to top left wing joint. Both actual wings are dead so while some of these are inconvenient for melee players they all can be reached and damaged by melee with a little bit of good timing and grappling.
I expect he is going to be dead within hours of this post.
Oh and PS/Edit: This is sort of common sense but apparently people are stupid. Do not zone in on him if you aren't going to fight him. Doing a "check in" regen's his health, dieing to him regens his health, using a wakestone regens his health. He has gained back something like 75% of a bubble in the last 30 minutes by the way.
