The mod adds weapon cases that wou will find in chests inside dungeon, strongholds and temples.
The weapon cases will work similar to Counter Strike, when you open the case there is a chance to get one special weapon. These are not cradtable. You open the case by right clicking the item.
Weapons can be Common, Uncommon, Rare or Legendary; and each type has different attack damage.
Also, the weapon can be either Broken, Good, Crude, Flawless or Perfect. Each state has different durability.
All these values can be changed in the mod's configuration file.
