Mutated Stones

You may have noticed that there are some spells that aren't listed in the vellum or magic stone section in Vigger's Shop.  These stones are called Mutated Stones.  These spells have to be created under special circumstances.  A mutated stone is made by creating a 'normal' magic stone, but during a red moon.  When this happens, the red moon's influence mutates the stone as it's being made, and creates a mutated magic stone.  This can be done during a yellow moon as well, but to a lesser degree; and even lesser still, a grey moon.  This can also work in reverse.  If you have a magic stone that you don't want, try and seperate do it during a red moon.. there is a chance of it splitting into 2 different materials than the ones used to make it, usually higher ranking ones (I.E. having a stone made from giant's tooth and slime goo seperate and give back to you giant's blood and slime jelly instead).  This is a good way to try and get all the different materials when trying to get 1 of each to do the Monster Shop thing.  You can also get one each of Mutated Stone by playing Gotz's Traps Lv.5.
