I would like to suggest a Valkyrie Sword for Lord Knights.
My suggested stats:
One Hand Sword:
Str+ 25 (More than Halberd)
Dex+ 10 (Same as Halberd)
HP+ 10% (Less than Halberd)
SP + 75 (Less than Halberd)
Atk Speed + 10
Increase Damage to Demi Humans by 17% (Same as Halberd)
Increase the Damage of Bowling Bash, Bash, and Magnum Break by 25%
Increase the Damage of Counter Attack by 50% (This is actually a useful skill)
