Improved Yrden is a mod for the game Witcher 3. It allows you to set the amount of different kinds of effects that can be active at the same time. For example, you can set 10 "normal" Yrdens (the Slow Effect ones) and 10 "shooters" active simultaneously (for a total of 20 effects). It is not possible to do this with a standard Witcher.

When installing this mod, you will need to download the corresponding patch for Witcher 3. If you do not know how to download it, then please read the instructions that are available on the official website.
