Remarks

• Impressive G-Lvl Dual Swords. Although they have high Raw power, they lack any Elemental power.
• The Grand Blos have a rather negligible -5% affinity. This can be fixed with Reckless Abandon for positive affinity. With even Reckless Abandon +1, these Dual Swords are easily the most powerful raw Duals in the game, as long as their sharpness can be kept up.
