Gnasher lizards make their lairs in stony areas, typically forest clearings or mountain terrain, usually near (within several hundred feet if possible) a water source. They are carnivorous creatures and highly territorial, even attacking their own kind if one gnasher lizard intrudes upon the territory of another. Gnashers are solitary creatures and only come together to mate (during the spring or early summer months). Mating season is the only time more than one of these creatures is encountered together, and once the mating ritual is ended, each goes its own way. The female lays a clutch of 1d4+2 eggs which hatch within 3 months. Young reach maturity within 8 months and are left to their own devices.
