Rune dragon

Rune dragons are a metal dragon accessible after completion of Dragon Slayer II.

They can be found in the Lithkren Labratory beyond the east barrier. To get back to the Labratory, you can travel using the rowboat from the quest or, after completion, you can take a Digsite Pendant and use it on the Strange Machinery north of the Rune Dragons, adding a teleport straight to Lithkren on it.
