1.0.6 (1.21.9)

Changed the damage thresholds at which Copper Equipment oxidizes, in order to make the Copper tier have more gameplay impact.
- Keep in mind each oxidization stage moves the equipment's stats toward Iron, with the last having Iron's stats.
- Exposed: 45% -> 20%
- Weathered: 65% -> 45%
- Oxidized: 85% -> 65%
