||Anaxial's Annex. These highly venomous serpents are very rare, but, despite their bizarre appearance are not chaotic. They have a head at each end, and, in addition to being able to slither like a normal snake, they can also grasp one of their heads in the mouth of the other, form into a rigid hoop and roll along the ground at high speed; this ability, however, will only work over reasonably even ground, so that the animal is forced to crawl if it wishes to enter hills or other rough terrain. How amphisboenae breed is unknown. Mind-affecting magics cast at an amphisboena, including sleep spells and the like, will normally affect only one head per spell.
The heads of the amphiboena are quite independant, so that they may attack separate targets if necessary. If the creature has sufficient space to do so (for example, if it initiates an attack against a prey animal) it will roll forward to build up momentum and then suddenly straighten out so that it catapults itself through the air and strikes the target like a giant missile.
