Interesting - I never thought of weaknesses like brittleness as 
properties.  Could magic remove the brittleness of an iron bar and make 
it stronger?  I had looked at brittleness as the lack of a property: 
flexibility and/or tensile strength.  That is one of the tough things 
about Perdo spells that remove properties: deciding what is a property 
in the first place.
