The level at which you can be reborn depends on what character class you are playing:

Archer: Level 120

Fire Taoist: Level 120

Trojan: Level 120

Warrior: Level 120

Water Taoist: Level 110

While most classes need to reach level 120 to be reborn, the water taoist only needs to achieve level 110. Water taoists have more positive karma and greater spiritual awareness than other classes, because they heal, instead of just destroying.

What if I'm level 130?
You can still be reborn at level 130. In fact, the higher your level the better. If you are reborn at level 130 or higher, you'll get more points to spend on attributes in your next life.
