- Weapon level
- Current refinement level
- Target refinement level
- Material selected
- Refining method
- Current GladiusRO refining configuration
The refining interface displays the applicable success chance before the attempt is confirmed.

When a refining attempt fails, the result may depend on the equipment, current refinement level, material, and selected refining method.
Possible outcomes may include:
- The equipment remains unchanged
- The refinement level decreases
- The equipment is damaged or destroyed
- The refining material and Zeny are consumed
Players should carefully read the information displayed in the refining interface before confirming an attempt.
Important: Do not assume that every refining material provides the same protection. Some materials may offer different success rates or failure results.
Safe Refinement Levels
Some equipment may have a safer refinement range before the risk of failure increases.
The applicable safe level can depend on the equipment category and current GladiusRO configuration. Players should check the displayed success rate instead of assuming that every weapon and armor type follows the same safe limit.
After reaching the applicable safe range, further refinement may involve greater risk.
