I may be incorrect since I have never used it ( why bother when I am already knee-deep in sliced bloody beast chunks?), but the status of diseased- lowers con and body building, the spell description mentions no damage, neither does the wikia. I will try it tonight for giggles, if it does do damage instead of just a debuff then thanks I hadnt tried it since its better to kill than debuff, and if so then I am wrong, and was uninformed as well.
