Achievements
After completing specific events and missions, there are achievements handed to individuals who desire to receive credit. In some cases, people must defeat a specific boss monster or save a specific person to receive the achievement. Some cases are less drastic than others. For example, one can acquire an achievement for collecting a certain number of words or joining a guild. Unlike Perks, Achievements aren't indefinite. This means that you must EQUIP achievements. In total, one can only equip 3 at a time. Achievements are not lost but it requires Jewel to change them. The flat price of changing 1 perk is 10,000 Jewel.
Example:
Wrote 20,000 words - Acquired an Exceed pet
