This mod is an unofficial add-on to the game. The main purpose of this mod is to add a healing effect to bandages. To achieve this effect, the developer decided to make them more effective. As you already know, in the game there are different types of bandages. But most of them are only effective for a certain period. And after that, they get less effective.

The way he did this was by editing the XML files. And as you already know, in the game there are different types of perks. And for each type of perk, there is a corresponding XML file. And in this file, there is a node containing the perk information.
