X'rphan the White Wyrm

The Frost Dragon, also called the White Dragon, is a high-level monster in Sword Art Online. It can be found on the 55th Floor at the top of the West Mountain. It is said to be capable of producing a rare mineral called «Crystallite Ingot», which is formed inside its body and, according to rumors, can only be obtained by a party with a master smith, however, it was later revealed that the mineral was actually found within the dragon's lair as its excrement.

Appearance
The frost dragon is a white dragon covered in scale-like crystal shards of ice. The dragon also has gigantic wings, huge jaws and ruby-red colour eyes.

Abilities
The dragon's attacks include slashes using both claws, a freezing breath attack and a blizzard assault. When the dragon opens its huge jaws and releases a hardened sound, the dragon is about to unleash his breath attack in the form of a wave of white gas. When the dragon flies higher than usual and fully extends its wings, it begins a blizzard attack by beating its wings forward and causing the snow below it to move.

As the dragon has wings, it may take off from the ground, thus normally players need to use long-range weapons like halberds or throwing weapons to bring the monster down to ground level.

Warmth of the Heart
Kirito and Lisbeth attempted to obtain a Crystallite Ingot from the Frost Dragon to forge a new sword for Kirito, but as the dragon was injured, Lisbeth came out of hiding to early and got blown away by the dragon. As Lisbeth was about to fall into the dragon's lair, a giant hole in the ground, Kirito jumped in to catch her and prevented her from taking fatal fall damage. As the lair was too deep and slippery to climb out of and had an anti-crystal field, preventing the use of teleportation crystals, the two were forced to spend the night there. After spending the night together, they managed to find the mineral, which turned out to be the dragon's excrement, buried in its lair, much to Lisbeth's disgust.

When the dragon reappeared, Kirito and Lisbeth rode on its back to escape its lair.
