Placebo

Placebo actually doesn't know much about medical knowledge, but he works with a Source Seer Noble to trick mages into trusting him. He's presents himself as an expert, and is often trusted due to his kind demeanor and appearance. But, in reality Placebo is only putting on a show, and is actually harming his "patients". Placebo managed to squeeze his way into his position with the help of his Noble friend, who let him... Bypass certain things. When placed into an actual medical situation, Placebo's true colors shine through, he really has no idea what he's doing. When confronted about being a quack, Placebo hides behind his Noble friend for support. Until one day... When that Noble was mysteriously murdered, leaving the quack doctor all alone with nothing to lean on...
