BrutusMUD offers 4 basic classes from the beginning, however at level 30 you specialize into one of 3 advanced classes (3 for each basic class). After reaching level 60 you can advance to legendary levels which offers new skills and spells and generally greatly enhances your character. To reach 5th legendary level, you have to come through special challenge, which will test your knowledge of your character. Thus only the best players can ever reach 5th legendary level. Of course you can try until you learn enough to succeed. Successfully completing the challenge opens whole new range of possibilities to advance your character far beyond limits of lower legends. But only few reached this status, and they are honored as gods among other mortals.
