OK since you may still not understand what to do exactly here goes. A - ask your mentor to fire you this way you get no exp loss and you can find a new mentor immediately. B - If he/she won't fire you resign and you will have to wait 3 days to take on a new mentor and you will lose some exp. There is no more mentor fruit it is a level requirement.
Find a mentor
You can find a mentor in two ways.
First, select a mentor from the mentor list, the mentor will receive your application immediately. After the permission he/she will be your mentor.

Tips: if you leave a mentor within 3 days, you cannot find a new mentor.
