The durability of most weapons does not loose durability when hitting some mobs or players.
Furthermore, all the weapons totally ignore the cooldown system introduced in the Combat Update of Minecraft.
All of this are very unbalanced, especially with the katana.

Which version of Minecraft are you using? The cool down system gets integrated later on... I just want to release the mod for many other versions in a similar way to 1.8.
The next update (0.7.2) will bring the Offhand-support and so on.

I'm using the latest version of the mod (0.7.1-hotfix1) with Minecraft 1.11.2.
And what about the durability loosing?

Ok, I will take a look at that, thanks for reporting :)

Fixed in next release :)

Thanks, keep up the good work!

No, problem. I thank you for reporting :)
