This both mods are working good but only in some cases like battle axe. But there are some issues too:

• long sword should have 3,3 range but have 2,5
• mace should have 2 range but have 2,5
• javelin, ninjato and francisca is not even having new animations
• war axe have wrong animations
• dagger have wrong or just weird animations im not sure
