• The thing about cobras is their poisonous bite. If you are injured in any way, you will generally heal over time. But the bite of a cobra makes you get ill over time; the two tend to cancel each other out. If you are bitten more than once, your health will actually decline; the more bites, the faster the decline.
• You will eventually shake off the effects of a bite (if you don't die first) but it takes a while. Fortunately, there is a cure, which you will occasionally find in bottles. One slug of cure does for one bite.
