Hey so I managed to get one more poem out and here is the prompt as usual I discarded the rhyme element, there are plenty of poets who have and continue to use it to great effect but for me full end rhyme does not work.
I wrote a charm against charm: http://www.napowrimo.net/2014/04/third-times-the-charm/
I would create a truly useful charm
A charm against charm
I could have used it more than once
A clear magnifying glass to expose charlatans
I would give it you in a locket
To wear over the heart to remind you
It will test the purity of others hearts.
