Would it be possible to have a de-leveler? Two reasons would be to do it.
1) I like to help others through certain areas with a special built char with special gear. Works best if I can party with them, but that requires the char losing XP often which takes a lot of dying. Plus would be a nice reward for the role playing of the char if I could transfer the XP to another char.
2) People make mistakes Leveling in the heat of action and mess up chars. Sometimes something sounds good but is not. Both of these mean a char redo, whereas with a de-leveler the char could be corrected very quickly.
I am thinking of an option through Celesti, where the XP would go to a player's pool.
