The mastery ranking system was developed and popularized by sages of the Argent Rose Society who wanted to provide a quick way to reference the level of skill and danger of creatures or missions. This would allow them to assign teams of appropriate ranking to missions that they should be able to handle. As it became known and used, it grew in popularity with adventurers and military organizations across the globe. They have been used to describe the power or threat of a single person or creature, a group, or even events such as a natural disaster.
These ranking have become a handy way of measuring a person's level of skill. While there exists a varied number of tests to measure someone's ranking, the simplest and easiest way is to have title claimants confront each other.
From lowest to highest:
- Leaf Novice (CR 1 and less)
- Wood Novice (CR 2 to 3)
- Copper Expert (CR 4 to 6)
- Iron Expert (CR 7 to 10)
- Steel Master (CR 11 to 14)
- Bronze Master (CR 15 to 19)
- Silver General (CR 20 to 24)
- Gold General (CR 25 to 29)
- Platinum King (CR 30 to 34)
- Diamond King (CR 35 to 39)
- Aetherium Saint (CR 40 to 44)
- Adamantine Saint (CR 45 to 49)
- Exalted Dragon (CR 50 to 54)
- Celestial Dragon (CR 55 to 59)
- Higher rankings theoretically exist, but are extremely rare to be found in the mortal realm, and are likely better suited to the realm of the divine.
Further breaking down these rankings, each rank can be categorized as either low-tier, mid-tier, upper-tier, or peak. These descriptors, spoken before the rank title, indicate how far along a ranker is to achieving their next rank. While creatures or threats with the same ranking indicate that there is close to an even chance of either side overcoming the other, the descriptors serve to add a bit more nuance to the rankings. For example, a low-tier steel master is someone who may just achieved that level skill, while a peak bronze master is on the cusp of ascending to becoming a silver general.
