Actually I don't have a clue about the odds, but a rather lucky reinc in my
opinion at least:

Abbess Abigail tells you, 'Although you have reincarnated I recognize your nun
soul. I will restore all I can.'
Abbess Abigail tells you, 'You lost 0 percent of the purity of thy heart.'
Abbess Abigail tells you, 'Part of your guild age was permanently lost.'

In addition, kept all the completed quests.
