I'm 71 Mystic Knight and doing post dragon content (after defeating Grigori).
Already gathered all the 20 wakestones, but haven't handed them yet;would have liked to try the UR Dragon but not sure if i have chances against it.
Have read online it can be faced in multiplayer,but as far as i know the game has no multiplayer, so maybe i mis-interpreted the forum?
This is my source but if someone here has already defeated it some advice would be appreciated.
Here's how it works (as I understand it)
everyone who plays online and fights the UR Dragon is dealing damage to a shared overall health pool - you don't directly fight the critter as a group, but everyone is contributing.
