I gave average damage formula and made some comparisons (eg., Khopesh vs Bastard Sword).
Attack formula (without additional bonuses):
Attack = d20 + BAB + Strength_mod + Size_mod
(this is a random variable because d20 is random)
Let's denote
R = Enemy_AC - (BAB + Strength_mod + Size_mod)
(this is not random variable for a given monster, I call it "needed Roll")
For actual damage you do several rolls (attack roll, damage roll, attack roll to confirm critical, etc.), i.e. your damage is a random variable, but it is possible to calculate the exact average value of that random variable.
Since that value depends on R (you meet different monsters) you can draw a graph - that is what I did.
1)
Bastard Sword wins here for absolutely all R (in
Plain case (i.e. with no bonuses, even Strength=10 here)):
Khopesh (red) and Bastard Sword (blue)
(high BAB means low R, high enemy AC means high R)
3)
If your weapon has
+5 Enhancement bonus, you have
Power Critical,
Weapon Focus and
Weapon Specialization feats then
Khopesh (red) and Bastard Sword (blue)
(no big difference, Khopesh is slightly better)
4)
If your weapon has
+5 Enhancement bonus and
Seeker +10, you have
Power Critical,
Weapon Focus and
Weapon Specialization feats then
Khopesh (red) and Bastard Sword (blue)
(now Khopesh is really better)
Obviously I should have taken Strength 20 instead of 10, but it was the first calculations, so I left it as it is.
If you want me to make some specific calculations then tell me:
- your weapon
- your weapon's enhancements
- your Strength
- your feats
- your enhancements
And I will draw the graph of average damage in various situations, i.e. for various R (I can compare several weapons on the same graph).
These calculations does not include (I don't have the formula for that yet):
But I can include many effects (i.e. the formula is ready for that) like:
- elemental, alignment, bane, sneak attack damage,
- even elemental burst damage, alignment burst damage,
- all feats or enhancements
