As we already know Glorious weapons aka KVM weapons are already op. But since new items coming in, Glorious Destruction Staff has become underwhelming. Comparing the Slaughter and Destruction formula:
[Slaughter] Lv 1: Increases physical damage bonus by (Upgrade - 4) ^ 2, til an upgrade of +14
At+14 = +100% dmg on demi-human and player
[Slaughter] Lv 2: Increases physical damage bonus by (Upgrade - 3) ^ 2, til an upgrade of +14
At+14 = +121% dmg on demi-human and player
[Destruction] Lv 1: Increases magic damage bonus and defense bypassing by (Upgrade - 5) * 2, til an upgrade of +14
At+14 = 18% dmg on demi-human and player (also mdef bypass).
As you can see the difference between physical and magical formula is unimaginably huge. In addition, the Glorious Destruction Staff is two-handed.
My suggestion is change the Destruction formula a bit: (Upgrade - 4) * 5, which at +14 = +50% dmg (just damage no need to change the mdef bypass).
This change would give a lot more love for magic players. <3
Thank you for your time,
One of many magic players.
