I don't know if I would ever call it broken.It's the temp hp each round that I found game-breaking, making it virtually impossible for enemies to take any party members down to zero hp. If the enemies focus-fired on the cleric they simply healed themselves whilst the wizard ripped them to shreads. The long range darkvision is situationally powerful, but not overly so on it's own, and clerics get plenty of good core spells so domain spells don't matter. Also, flying.
But that's my experience, which was it's game-breaking. Other playstyles may differ.
its just turn out like something that you wouldn't allow at a table if was homebrew because it's not really a coherent theme. What does the temporary hit points, armor/weapons, and floating around like a balloon even have to do with anything?
