Reputation is something players can earn by challenging their fellow players in the Arena. Based on a players rank, they will receive regular awards in Gold and Reputation.
In the Arena, players can challenge AI controlled characters of their fellow players to see who is top dog. When a player defeats someone with a higher rank than their own, they will move up in rank, and their opponent will go down by one. After defeating an opponent, the player will get 2 Reputation. When you rank in the top 1,000, every fight you win against a higher-ranked opponent will award you 88 Diamonds
Based on these rankings, awards in Reputation are sent out every day between 10pm and 12am server time.
