try crusading for this instead:

Bards have cancel magic, cure poison and cure disease. However, bard cure disease and cure poison is broken, and has been for a long time (years? decades? I can't keep track). It worked, badly, for a short period of time, but somehow, that technology was broken or lost. I'm sure if someone asked the developer that made the change that broke this, his response would be "bards? Oh, I hadn't thought of bards."
