If you have been saving up bones like i have u my know that befor bones like (White Minnoth Ribs) have gone down befor they were 50,000mp and now there 1900mp so i recomed that u get bones when there cheap are u might be in a pickle in the next round of TWINS AKA Rusty quest.

P.S. so if u have i think u are a very smart person to do that cause u have more chances to get the rusty potion and make milllions andif u dont lets say u have a less chance of geting it inless u have a lot of money so keep collecting those bones and u might get lucky
