Grand Chase Exclusive In-Game Item on the FilePlanet Free MMO Club
Exclusive FilePlanet Subscriber Benefit:
Receive a unique in-game item, a special "egg suit"!
Not exactly free. It's $6.95 (USD) to subscribe. I'm not sure for the stats and when it's released. It's not in the Event Title Page. I hope this is for Grand Chase USA. Seems like it.
