The teeth of a dragon can be deadly, and if you've been bitten, chances are you'll catch dragon fever. This fever can cause serious illness or injury, and you must be careful to treat it with the proper materials. Fortunately, being bitten doesn't mean you'll turn into a dragon - that would be truly drastic. But there can be lingering side effects from a dragon's bite.
You may become subject to allergies you've never previously had. Virgins may begin to follow you around. Possibly unicorns too, if you live in the right part of the world. But the hope is that you not be bitten at all, of course.
To stay protected from dragon bites - and therefore, dragon fever - be sure to wear chain metal on both arms and legs, in addition to the upper body. Stay away from unexplored caves and deep ravines, and be careful not to make any noises that sound like a braying goat.
So stay safe and keep the dragons at bay. Good luck.
