Ahh the Khopesh.
long has it been considered as one of the best one handed weapons. This is still true from the basic ratio perspective.
With the advent of a variety of changes in the game it has increasingly become less and less viable to spend a feat to gain proficiency.
There have been only a few decent named khopeshes. None of them were good enough to combat the rise of other weaponry.
With the release of the Vistani Tree the dagger can now be superior to the khopesh. Increases in attack speed aside the critical potential of a dagger can now surpass the potential for a khopesh. I find this slightly rediculous as the dagger is a simple weapon.
A variety of other single handed weapons have had there potential critical and ranges enhanced via swashbuckling.
Moreover, other exotic weapons have within the proficiency feat an additional benefit such as the vorpal knockdown of the great crossbow or the glancing blows of the dwarven axe and bastard sword.
Taking all these changes into consideration I believe it would be appropriate to add an effect to khopesh proficiency.
Some of my Ideas are:
1d8 Bleeding damage that perhaps stacks to 5d8.
10% Stacking Fortification bypass.
2% on hit slow that stacks to 10%.
suggested by Cleanincubus:
Bonus to trip DC
suggested by Daine:
Bludgeon damage type
Parry AC bonus
Additionally, or alternatively It would be nice to have a follow up feat (similar to shuriken expertise), call it khopesh expertise.
Some ideas for this are:
Stacking attack speed.
Melee power.
+1(W).
I would love to hear some other ideas to make khopeshing more fun and viable.
