I don't know how feasible this is, but I just saw an interesting concept by a random FANDOM dude on the Equipment Modifiers page. Based on that, I had this idea to combine the Modifier system with Lore Texts.
Let's take my lore text as an example, Longbow Etiquette. If you put that book and a bow in the anvil (provided you have strings too), you'll be able 'enchant' the bow with a good modifier. It's like enchanting an item with the Flame of Udûn or the Chill of Daidelos, but instead of a cool and special magical effect, lore books can only add common, but high-level, modifiers.
For now I don't think we have many lore texts about weapons, but that can be worked on.
The first person to shout "but muh realism" will be thrown out of this room through the nearest window.
