Guilds are groups of players who compete in ranked battles to earn collective rating points and demonstrate superiority over their foes. Anyone can start a guild by performing a founding ceremony.
Season rating points are won and lost by competing in regular Card Hunter ranked battles. A win against an unaffiliated opponent earns 1 point, and a loss costs the same. Matches played against members of other guilds however earn and lose points via an Elo system, similar to the rating system used in Card Hunter itself.
A blitz occurs if the loser of a battle scores fewer than two stars, or the winner scores fewer than four. In the case of a blitz the rating points earned or lost are doubled!
