Basilisk

Stone Gaze (Gaze). The basilisk targets a creature within 60 feet. The target makes a DC 13 Constitution saving throw. On a failure the target magically begins to turn to stone and is restrained. A lesser restoration spell ends this effect. At the beginning of the basilisks next turn if still restrained the target repeats the saving throw. On a success the effect ends. On a failure the target is petrified. This petrification can be removed with greater restoration or similar magic or with basilisk venom.

Venomous Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) piercing damage plus 10 (3d6) poison damage.

Stone Glance. If a creature within 60 feet that the basilisk can see hits the basilisk with an attack, the basilisk uses Stone Gaze on the attacker.
