The Prophet is an expert in supplementary magic. Supplementary magic mainly strengthens allies. Prophets must possess heavy equipment and extra strength before fighting monsters. Prophets strengthen the force of their party, especially during battle.
Their supplementary magic increases attack power, hit rate, evasion and defense.
To be a Prophet, your level must be over 40 and you must collect the Mark of the Pilgrim, the Mark of Trust, and the Mark of the Reformer.
