All Stats: +50, Weapon ATT/Magic ATT: +50, MaxHP/MaxMP: +1000, MaxHP/MaxMP: +5%, Ignore Defense: +40%, Boss Damage: +40%, Critical Damage: +10%

All Stats: +50, Weapon ATT/Magic ATT: +50, MaxHP/MaxMP: +1000, MaxHP/MaxMP: +5%, Ignore Defense: +15%, Boss Damage: +20%, Critical Rate: +5%

They also listed it in a way that made people think that each additional set effect stacked upon the previous, when it reality it was a cumulative set effect.
