In YGGDRASIL, Swamp Nagas were one of the monsters that spawned around the swamp area where the Great Tomb of Nazarick was located originally. It guards the unconquered Great Tomb of Nazarick from enemy players and NPCs if caught on sight trying to trespass into their territorial ground before reaching the tomb.
Swamp Nagas have a similar appearance like any other type of Naga. They possessed an upper humanoid body with the lower body of a snake.
Swamp Nagas are Naga sub-species that have adapted to living in a swamp-like environment. In YGGDRASIL, their level can reach as high as level 80.
