It's been a long-sought feature, but after the images made by Rufus (

So, after talking around a bit, I went and made this concept video of what achievements may look like if implemented in GraalOnline Classic:

Summary
Stat Milestones
Players unlock achievements when they attain a set number of PKs, spar wins, or defeat a certain amount of enemies. Rewards are given for each achievement.
Misc. Achievements
Other achievements are available for doing certain things in-game such as obtaining a certain item, or discovering certain secret areas on the map. Rewards are given for these, ranging from gralats to character graphics, items, or sometimes even furniture for your house.
Achievements Profile
After opening a friend's profile and More Actions, a new option is available that allows players to see achievements unlocked , the dates and rewards gained. There may also be an option to compare achievements and scores with friends, within guilds, or even between rival guilds.
Game Center Integration
The in-game achievements are sent to Game Center, which allows anyone to share their records all over the world.
If you like these ideas, please give reputation for Rufus as well ^_^
