Boalisk

In the Dungeons and Dragons fantasy roleplaying game, the boalisk is a magical beast, created by crossbreeding a boa with a basilisk. It was introduced in the D&D module S4 - The Lost Caverns of Tsojcanth and later reprinted in the Monster Manual II.

Typical physical characteristics
The boalisk resembles a 25 foot long constrictor snake, and it dwells in the tropics. Though the boalisk lacks the numerous legs which is a signature of the basilisk, it does have the eye weapon; any who meets its gaze are infected with a rotting disease similar to that which is inflicted by the mummy. Even if the boalisk's gaze is not met, mere knowledge of its presence will inflict armor damage instead. The boalisk can also use normal bite and constrict attacks. Boalisks cannot talk, being animals.

Alignment
Boalisks are true neutral in alignment.
