||Hand this stone into Milos (Edron magic academy, second tower, 4 levels above ground.) or Trimegis (Thais) located here. You will recieve 5000 * your current level in experience.
This stone was extremely valuable right after it was released on September 1, 2010 because there was no limit to how many stone of wisdom you could use at a time. The stone of wisdom was created for the intention of providing players an easy way to recover their lost experience while doing the Rise Of Devovorga world quest. However, due to the abuse of such item from some players, this item was then adjusted by Cipsoft in the next update. Currently,the stone can be used at any level but only 1 stone can be used per month. Needless to say, this adjustment to the item drastically dropped its price. However, some high levels would still pay a pretty penny for one of these.
