The Mad Bull is one of the best monsters for players below level 15 to train on. Being of Defensive type, the Mad Bull will not attack players unless attacked first. This allows for players to train in a patch of Mad Bulls without needing to worry about being attacked. The farms on the east side of Central Valley present the perfect place for a player to train before starting on Aggressive type monsters such as the Wolf or Bear. Mad Bulls are also killed to collect Mad Bull's Horn during completion of the Banker Don's Hobby quest.
