The Undines originate from the Crescent Gulf in the Wetland Areas of the east and claim the Rainbow Valley, one of the three large pathways to the World Tree. The Undine Capital, a castle-like structure, is bordered by the Spriggan territory to the north and the Imp territory to the south.
The Undines are typically associated with the color blue. Similar to the other races, the Undines are capable of flight and are also one of the five lightweight races, allowing the Undines to use the Wall Run skill.
Flight: Similar to the other races, Undines are capable of sprouting wings that allow them to fly.
Support Magic: Though capable of using other types of magic, the Undines are experts in using high-ranking recovery and support magic due to their high-level magic capabilities.
Underwater Combat: Due to their affinity with water, Undines are experts in underwater combat. This makes them valuable assets when faced with water-type monsters.
Wall Run: As one of the lightweight races, the Undines are capable of using the skill Wall Run, that, as the name suggests, allows them to temporarily run on walls. The normal limit is a distance of ten meters, but those with an extremely high sprinting speed are known to be able to run for about thirty meters.
