The Dragon is one of two boss fights on the map, making the strategy easier since there aren't many mechanics to avoid. As long as you have the Guard of Fafnir, you are unkillable by the Dragon Fire if you have your shield out. You can use this to keep you safe as you run around the arena in between damage phases. A damage phase begins once Nikolai harpoons the dragon, creating a weak point for you to lay into the dragon.

You'll have to survive the Dragon Fire in between damage phases, then quickly shift to doing damage once the harpoon has hit the dragon. You can read our detailed boss fight guide for more information on how to deal with this boss fight and prepare for the next one.
