Achievements

Achievements are completable events that trigger when you finish the criteria it specifies.

Most achievements are simply there for extra content in the form of challenges (getting a higher dungeon rating), fun (using emotes), or completing content (Hitting a certain character level). There are some achievements however that give Titles, which are equipped names that can give you enhanced stats.

Active Achievement
The Active Mission system (Active Achievement in-game) was implemented by Nexon on 4-17-13. When entering dungeons, an active achievement may be given to the player. There is a chance of not receiving a mission, and the mission itself is randomized. Missions include, but are not limited to: If the requirements are met, upon completion of the dungeon a gift pouch will be sent to the player's mailbox. The grade of the gift pouch depends on the player's level, and its content depends on the difficulty of the dungeon. Rewards include sparks, lustres, rare titles, and crafting materials.
 * Complete the dungeon in 8 minutes
