Fought Jormag's Claw dragon last night. It's by far the most interesting of the dragon fights, but I think that's only because they execute the layers of the fight better and enforce them more than the other two fights. Jormag has multiple phases. In the first phase, he flies overhead and drops ice claws onto the ground which spawn Dynamic Events to take down the claws and the champion level mobs they spawn.
That's the point where CG and I wandered in, unwittingly, to the start of the dragon fight. We were basically mob-skipping and gathering nodes and food items, when the Dragon flew overhead and dropped a nasty on us. The moment where you hear the dragon and see it's large ass shadow pass over you is pretty cool.
After this first phase, the dragon rears up and faces the little war outpost nearby. The outpost has cannons that fire on the dragon's wings to bring him down, but when the dragon lands, it creates ice walls in front of him to protect from the cannons. Then you have to break down the walls and deal with some add spawns. Once you break down the walls, you can start hitting the dragon. At about 25% intervals, Jormag's Claw will rise up into the air again. At this point, lots of Champion level adds come from the cliffsides (you fight on a mountain, mainly fighting at two cliff edges and the battlepost in the middle of them) and attack the cannons and explosives at the outpost. You have to protect the ammo and cannons, and take down the Champions. Once you cannons are freed up, they fire again on the dragon. Everytime this happens, Jormag makes a run at the outpost from the air, and the sky explodes with anti-air fire. Then the dragon lands from the hits, and it goes back to the ice wall stage.
After you go through this enough times to get the dragon down to 25%, it flies up and takes one last big run at your battlepost. This time the cannons hit hard, take out the dragon's wings, and the dragon bounce crahses off the mountain and lands on the other cliffside. I thought that was the end of the fight, but instead, the dragon refuels without its wings and goes back to 100% health, but can no longer fly. Now he summons repeated Champion mobs from the cliffsides, and creates little ice spikes in the ground. Up close, he does a lot of damage. The Vigil and Kodan (two factions fighting with you) then send in Golems carrying bombs that need to navigate through the ice spikes and adds, and then suicide bomb the dragon. So this final phase consists of protecting the golems, while hitting the Dragon. clearing ice spikes and doing all the battle rezzing and helping that the fight has been full of so far.
After you whittle down his health with golem bombs and attacks does the dragon finally perish, and the treasure chest drops.
I have screens if anyone cares, but I thought posting how the fight went was more interesting.
