The Enhancement System Witcher 3 Mod
The Enhance System for The Witcher 3 has only been available to download since Dec. 26, 2015, but it has quickly become one of the most popular mods for the game.
This mod brings a whole host of changes. For example, Geralt will be able to use weapons previously locked to NPCs, while there are also upgrades to each of the relic swords in the game. Armor, crossbows, and DLC equipment have all been enhanced. In the case of crossbows they are now upgradable, allowing you to deliver more damage with your arrow-firing beauty. The crafting system has also been tweaked to make a little more sense. For example, swords that are a dark color will need to be made with a Dark Steel Ingot. You can find the mod on Nexus Mods, and under the Posts tab there are more details about what the mod does.
