# Rebirth System
The Rebirth System lets players reach Level 85 and “rebirth” back to Level 80 in exchange for rebirth rewards. This creates a repeatable progression loop with incentives for continued leveling.
How it works:
* Your character must be Level 85 to rebirth.
* Logout or go to Character Selection before rebirthing.
* Visit [shop.aionoverdose.com/rebirth](https://shop.aionoverdose.com/rebirth) and log in.
* Select the character you want to rebirth, then click Rebirth Character.
* Log back in and check your in-game mail to claim your rewards.
Rewards:
* Experience Mark - 50pcs
* Ancient Crown - 15pcs
* Ultimate Etium - 2pcs
* Fighting Spirit Fragment - 40pcs
* Rebirth Coin - 1pc
* Overdose Shard - 20pcs
You can exchange your Rebirth Coin in Rebirth Coin Exchanger located at Sanctum and Pandaemonium.
