Grid Master/Combat Masteries

Combat masteries are a returning system to Grid Master that offer boosts to combat. Completing certain grid tasks will increase all three combat masteries by one tier. This is different from the original implementation in Raging Echoes League, where players chose only a single mastery to rank up each time.
