'k, you balance maniacs, tell me if I need to adjust this:

Niks is capable of generating a blob of liquid or gas-like substance that inflicts symptoms of diseases the size of a volley ball. Inflicting the disease is a matter of soaking or covering someone with the liquid or gas in the blob. Hitting the blob would cause it to splash or disperse. The symptoms range from nausea, fever, paralysis, diarrhea, etc. Niks is also able to combine the symptoms. The symptoms are magically induced, as such, most mundane treatment would fail and even the healthiest (or disease immune) person will fall prey. However it can be removed easily using curing magic. There're currently so many symptoms Niks can create at a single time. Maximum range of 75 yards. The Miasma can also be used to analyze unknown poison and disease in a body. Once analyzed, Niks can then create them on its own through miasma. However, this application requires touch and undisturbed concentration.
