The SOL Rebirth System extends the character development and was first introduced in Sept. 2008. More specifically, the first rebirth is designed for characters reaching level 90(level cap) and gives increased stats, special skill boosting damage, defense, and HP, exclusive privilege to orange gears, and double XP in in-game events. The rebirth was related to phoenix reincarnation story in that characters have to restart at level 60, spend time, effort, and patience to get to the top of the ladder again.

In upcoming game update next week, SOL will open Second Rebirth. The second rebirth works in a similar way and is designed for characters that have gone through the first rebirth and again reached level 90. Through the 2nd rebirth, characters will start at level 60 and entitled to red gears and triple XP in in-game events(beach turtle, mushroom cultivation, escort mission and sparkling labyrinth). All skills and gears that available to them prior to the 2nd rebirth remain available. The rebirth is done at Rebirth Guider NPC in main cities. The red gears added to this update will be the highest grade ever in the game. They require materials, gold, and black irons to craft. The black irons are dropped from bosses in Burningblood Purgatory.
