What is a revocation in dragon quest ix?

Answer 1

'Revocation' is when a character who is Lv99 in one vocation has their level reset to 1, by Jack of Alltrades Abbey.

This might not seem worthwhile since the character's stats go back down to that of a Lv1 in that vocation. However it means they can earn more skill points. As an added bonus, the first time your main character revocates in each vocation, he or she will receive an item from Jack, one relevant to that vocation.

Secondly, the quality of the treasure in grottoes will go up, the more the main character has revocated. By that I mean, an unrevocated character may never see a single 'S' rank chest in even the highest level grottoes. But one that has revocated 10 times may see several in a single grotto.
