Finding it at the bottom of the [[Fungal Caves]] and defeating [[Sieni Fusanga]] are only half the battle since the stone is in the middle of a small underground lake. If you have gained the [[Swimming]] status from a fountain, this is no problem. Otherwise a [[wand]] or [[ring]] of [[Polymorph]] can easily change you into a flying/ethereal/swimming creature to grab it - but be careful about transforming into a weak creature around strong enemies. The [[belt|belt of levitation]] from defeating Huang Ming Pong will also work, but you can '''instantly drown''' if it is broken or removed. You can also zap it with a [[Wand of Teleportation]] and then search the level to find where it landed.
