This magical stone appears to be any one of the other sorts, and testing will not reveal its nature. 

However, as soon as the possessor of a stone of weight is in a situation where he or she is required to move quickly in order to avoid an enemy — combat or pursuit — the item causes a 50% reduction in movement, and even attacks are reduced to 50% normal rate. 

Furthermore, the stone cannot be gotten rid of by any means throwing it away or smashing it notwithstanding — and it will always turn up somewhere on the character's person. 

If a dispel evil is cast upon a loadstone, the item will disappear and no longer haunt the individual.
