Experience points after Reincarnation(s)

Experience required to level is increased after your True Reincarnation.

The math is "Current Base XP (for current level) + Original Req XP * 1+(0.05 * Current level)" for the first reincarnation and 10% for the second reincarnation (and same after).

Experience Points to Level After One True Reincarnation
 

Experience Points to Level After Two or more True Reincarnation
After two True Reincarnations, experience required is even more.
