Nomads are basically humans, though never actually referred to as such in-game. "Nomad" specifically refers to those who have gone to the Downside, either by choice or by exile. They are said to share a common ancestor with Harps, descended from the ones outcast for being born wingless.
Nomads who survive in the Downside for long enough eventually transform into Demons.
Nomads are a flexible all-rounder class with balanced stats across the board and very standard abilities. Their cast has decent speed and range. With the right masteries they can specialize into an offensive or support role.
The first branch improves offense and scoring, the second branch grants Nomads team support abilities.
