All giant snakes are carnivorous and can be found in every type of climate except for the coldest.

Boas will drop on its prey from above, coiling its long body around the chosen target victim and attacking by both biting and squeezing for 2d4 points of damage. Once a snake has a victim within its coils it is quite difficult to release him or her. Several strong creatures creatures can grasp each end of the snake and uncoil the victim in 1d4+1 segments. Four very strong humans, 16 or greater strength each, should be able to accomplish this task. Attacks directed against a snake will also affect the victim trapped within the snake coils, though the GM may allow certain types of attacks to not do so.
