Hello Survivor!

We definitely understand how frustrating it can be when an upgrade attempt doesn't go as planned, especially when you see your weapon downgrade! Thanks for reaching out and sharing your experience.

To clarify how weapon upgrading works in Darkest Days, you've hit on the key mechanics:

Target Enhancement Stage +0 to +1: 100% Success Rate, No Downgrade
Target Enhancement Stage +1 to +2: 50% Success Rate, No Downgrade
Target Enhancement Stage +2 to +3: 50% Success Rate, No Downgrade
However, starting from +3 to +4 (and all subsequent upgrades from +4 and up), the mechanics change. There is indeed a 33% Success Rate, and a failure will result in a downgrade.

So, when you attempted to upgrade from +3 to +4 and it failed, your weapon correctly downgraded back to +2 according to these rules. It's a challenging system designed to add a layer of risk and reward to higher-tier enhancements.

We hope this explanation helps clarify why your weapon returned to +2. Good luck with your future upgrades!
