This item may be obtained by training Runecrafting via making runes at altars, including the Ourania Altar, or in the Runespan. Gaining a pet is based on the amount of experience awarded at once; the more experience granted, the greater the chance of gaining a pet. Additionally, it has been found that Rue is obtainable from converting unstable essence. Thus, this may have the potential to increase the odds of obtaining the pet due to having a large influx of experience all at once from converting unstable essence at high-level Runecrafting altars. The chance is not affected by experience boosters.
- She is a pet version of the greater dragon summoned when using the greater conjuration platform found on the top floor of the Runespan.
- During the 2017 Christmas event, Rue was obtainable by channelling the Energy rift.
- The word Rue is similar to Ryū, the Japanese word for dragon.
