Aristotle's Matter alteration Spell

E/F/M:

This magickal operation enables the caster to cause the permanent transmutation of non-magickal item into another similar sort, including base element to base element. Soft wood can be made into hardwood; bone can be transformed to ivory: one sort of crystal can be made into another kind. In general, the new material retains its size and shape in the transformation, subject to weight consideration. That is, if the new material is of greater density and weight than the former, then only as much weight or volume as would be normal for the new material will exist. Thus a pound of iron turned to a pound of platinum would have a final volume considerably smaller than the original. A soft crystal of topaz made to much harder corundum would likewise be smaller. Note that any dispelling or negating Heka contacting such altered material will return it to its original material state.
