Warcryers specialize in party play. A Warcryer uses a spell called Song of War to heal and increase the fighting spirit of his comrades. They increase attack speed, evasion and critical attack power of party members. He is also capable of disrupting opponents with his song.
To become a Warcryer your level must be over 40 and you must collect the Mark of the Pilgrim, the Mark of Glory, and the Mark of the War Spirit.
