Kappa are obviously inspired by the Kappa of Japanese mythology, which are "water imps" that usually resemble turtles.
In game all Kappa are simply labeled "Kappa", but they vary in habitat, size, levels, skills, and drops. For easier identification in this wiki these different types are sometimes referred to by a sobriquet according to the type of Kappa Shell they drop:
|Shing Jea Island||Kappa "Hatchling"||Kappa Hatchling Shell||1|
|"Elder" Kappa||Elder Kappa Shell||10|
|Kaineng City||"Ancient" Kappa||Ancient Kappa Shell||20|
|Jade Sea||"Archaic" Kappa||Archaic Kappa Shell||23|
The sobriquets (Hatchling > Elder > Ancient > Archaic) imply that Kappas can reach great age (possibly in the hundreds or even thousands of years). Obviously their power (level) increases with their age.
|Shing Jea Island||Kaineng City||Jade Sea|
|Turtle Shell||Turtle Shell|
|Ice Spear||Ice Spear|
|Water Attunement||Water Attunement|
Note that the Level 20 Kappa from Kaineng City almost have a completely unique set of skills compared to other Kappa.
- According to Sujun on Shing Jea Island, the collective noun for a group of Kappas is a pride and they are very fond of cucumbers.
