# Arena
A Guild's Arena level determines the level of Brawl they will be able to play, as well as the amount of participating players and rewards that can be earned.
For performing well in Brawls, guilds will be rewarded with CROWNS. These are a special, non-transferable, non-tradeable guild currency that will allow the guild to upgrade the arena and other buildings as well as purchase items for the guild in the guild shop.
The **COST** to level the Arena is a combination of [Guild Power](https://support.splinterlands.com/hc/en-us/articles/16490875461908-Guild-Power-FAQ) and Crowns. Crowns can only be earned through Guild Brawl combat.
**FRAYS** are the number of players allowed to participate from your Guild in a given Brawl. A Fray always has set League and card limitations, and the Guild must strategically find a player who matches each fray.
The **MAX TIER** determines the level of play among the Frays in a Brawl. Tier 1 contains mostly beginner-level Frays, while Tier 5 contains higher-level Frays, such as Gold and Diamond. Additionally, Guilds are always matched up with Guilds in the same Brawl Tier.
The **Rewards** represent the maximum Crown multiplier that may be applied to the Guild's earnings for victory.
