Questions and answers about ERM scripts for WoG.

Could you tell me if it’s possible to modify an existing script? The idea is that at the beginning of the week, roaming monsters appear on the map, and for the entire week, only these monsters have improved attack, health, and other parameters. However, I want these improvements to persist even after the “Monster Week” ends, meaning they would be permanent until the next week of the same monster. In other words, with each iteration, all the creature’s parameters would improve and improve. I’m not worried about imbalance because it’s very rare for the same monster to have its “week” again. In the picture, you can see the name of the script that is responsible for this. I just want to modify it. What do I need to do? Or maybe someone could do it for a fee?
