Basilisk
Basilisk are great reptilian monsters with 8 legs which is believed by some to be so venomous, it leaves a wide trail of deadly venom in its wake, and its gaze is lethal. Some claim its weakness is the odor of the weasel and the tears of a griffin.
The heroes defeated two basilisks which were occupying Entemoch's Boon. Bree obtained a basilisk egg.
