It increase damage of two-handed weapon as sword, axe, katana, hammer, blade, spear.
I think that standart values of weapon damage in the game could be higher.
So, I create this mod.

Ordinary weapon damage increased at 50%.
For example: Stone Sword - 19 + 50% = 29, Ancient Two-Handed Sword - 40 + 50% = 60, Longsword - 27 + 50% = 41.
Exceptionan weapon damage increased at 65%. For example: Exceptional Longsword - 29 + 65% = 48.
Flawless weapon damage increased at 80%. For example: Flawless Longsword - 31 + 80% = 56.

As you can see - now for Longsword damage value is 41, 48 and 56.

I think it is more interesting when you create advanced weapon and its damage value differs from ordinary at 8 - 20 points, instead 2 - 3.
