Lump of stone (Magical construct)

The lump of stone is an item from the new skill Dungeoneering. The stone is part of a Dungeoneering puzzle in which you must repair a giant stone guardian by using a hammer and a chisel to carve the lump of stone into a body part that the guardian is missing which is either his arm, leg, or his head.

When you right click on the stone there are four options, Use, Carve, Drop, and Examine.

As the stone is only supposed to be part of Dungeoneering it is not supposed to be taken from Daemonheim. But a glitch on Wednesday, April 15, 2010 caused one player "EREMUE" to take the stone into Runescape outside of Daemonheim.

The stone cannot be found in the Grand Exchange though it is tradeable and worth only 1gp.
