Hi,
I want to suggest Explosion Blade lvl 380 wep for MG to be done in one hand.
I think it's fair since for sm, bk, dl, sum, all weapons are one handed and can be combine with a second weapon or shield.
While for MG all power slash magic weapons except Runebastar sword, seed wep are two handed.
Without a doubt, Explosion Blade is the best PVM weapon combo with the Muren Set.
But I believe that one can also think about this issue, how not to lose MG from dmg for pvm.
Like add pvm dmg for Power Slash spell.
But in the case of my suggestion, I think it would improve the look of the MG.
And maybe it would make this sword attractive for players.
Let's not forget that together with Sylph Wind bow cannot be used for statue combination.
Which makes it unusable, but it's actually a good weapon.
