Fighter
One of the four character classes in NERO is a Fighter. Fighters may learn any skill, but weapons skills and general increased damage cost less Build Points (BP) for them to buy then any other class. Fighters get more Body Points per level than any other character class.
Templar
One of the four character classes in NERO is a Templar. Templars are a mix between Fighters and Scholars, and may learn any skill, though the cost varies by what is considered to be a skill that at which a Templar is naturally adept. Templars get Body Points at the same rate as Rogues, which is half the rate of Fighters.
Rogue
One of the four character classes in NERO is a Rogue. Rogues can buy any skill, but increased damage while attacking from behind a foe and other "rogue-like" skills (Disarm Traps, Pick Locks, Waylay, etc) are the least expensive for Rogues. Rogues get Body Points per level at the same rate as Templars.
Scholar
One of the four character classes in NERO is a Scholar. Scholars are primarily spell casters, and tend to choose one of the two types of magic schools as a primary school to cast. They can learn Read/Write, Read Magic, and other scholarly skills for the least amount of BP of all of the character classes. Scholars get Body Points at about half the rate of Rogues and Templars, so they are best when not in the front lines of a battle.
