Like all snakes, amphisbaena have poor eyesight, but are able to sense warm-blooded creatures accurately within twenty yards. Lanterns or torches will confuse them, reducing their I by D6 x 10 for that round.
A giant snake, with a head at either end. An amphisbaena can reach over twenty feet long and even a small one would be over ten feet.
Amphisbaenae fear fire, but otherwise they are immune to all psychology rules. They cause fear in living creatures under ten feet tall.
Amphisbaenae may bite with either end or both heads or may constrict. Characters hit by a constriction attack must check to see whether their arms are free or not and can only escape either by making a test against S x 10 or by killing the creature. Bite attacks are venomous and characters failing a Poison test (T x 10) will die in 2D6 rounds.
