🎯 Tips & Tricks
Use a mod manager like Vortex or MO2 to avoid manual file placement issues.
Check if you need to craft the weapon or find it in the world — the description doesn't say, so look for in-game clues or comments.
Since it's an older mod, test it early in your playthrough to ensure it works with your current load order.
