Basilisk

Squat, eight-legged reptiles whose lethal stare locks flesh into stone. They lumber through caverns and overgrown ruins ringed by statues of creatures frozen mid-flight, and the faint reek of their venom is the only warning of a lair best left unentered.

Venomous Bite: poison, melee 5 ft, +2 to hit, 2d8+4 piercing and save Con Tough, 1d8 ongoing poison on a failed save, cooldown 2 rounds. Petrifying Gaze: control, 30 ft, save Con Tough, restrained on a failed save and petrified if it fails the save again at the start of its next turn, cooldown 3 rounds.

Stone Reflection: if the basilisk is forced to meet its own gaze in a mirror or polished surface, it must save Con Tough or be petrified by its own power. Senses: Thermal Vision (60 ft), Keen Smell.
