Melee weapons used to be found with randomly selected prefixes/modifiers. This mechanic has been cut from the current version of Darkwood.
The modifiers were randomized with every melee weapon. The prefix would affect the weapon's damage, stamina cost and durability. This modifier of a weapon could be changed by using a Repair Kit, an item that has also since been removed from the game.
The weapon prefixes have been effectively replaced by the Workbench weapon upgrade system.
