🎯 Tips & Tricks
Since this mod is from 2013, check if your Skyrim version is compatible — you might need to use a mod manager to handle any potential conflicts.
Expect a steep difficulty curve; consider lowering the game difficulty if you're not used to hardcore combat.
Make a separate save before starting the mod so you can easily revert if you get stuck or encounter issues.
