most efficient level to use my monster stones at

[auburnfan870]

started a warrior 2 days ago on altar and going to level straight to 83, i am currently 75 with 16 monster stone. what is the most efficient level to use them at? 79, 80, or 81? thanks im a little rusty on when xp is cut

U can start now ��

[auburnfan870]

it seems my answer is to do them all at 79 in the duration of a bdw scroll to get the most out of it. thanks

Or you could put em in magic bags and wait for a 50% xp event.

or just wait xp event and combinate with bdw scorol
