  • Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 14 (2d10 + 3) piercing damage plus the target is grappled (escape DC 13), and the cavern lizard can’t grapple another target.


A 10-foot-long gray lizard with large wide feet and sapphire-gold bulging eyes stares. Balanced upon thick and muscled, its feet cling to surfaces upon small suction cup-like pads. Its head is angular and somewhat flat and its mouth sports a row of long, serrated teeth.

These large magical lizards, readily identified by large bulging sapphirecolored eyes, are found only in the darkest underground places and never venture to the surface world.

A cavern lizard is typically very aggressive and often travels far away from its lair in order to hunt. While not territorial, a cavern lizard is rarely encountered with others of its kind. Each cavern lizard often has a hunting ground covering up to 2 miles in the Under Realms.

A cavern lizard’s lair is a large expanse of interconnected caves littered with the bones and scattered remains of its victims (including treasure). Hunting cavern lizards usually drag their kill back to their lair before devouring it. If young are present in the lair, the kill is divided between them. Young cavern lizards resemble their adult counterparts in all respects, save their eyes are a dull blue. During mating season (late summer, early fall) 1d6 eggs may be found in the lair. Eggs are round in shape, leathery to the touch, and gray in color.

Cavern lizards are aggressive ambush hunters. They prefer to scale the walls and wait for prey to pass underneath them where they drop down on their unsuspecting meal. In most battles, once a cavern lizard bites, it hangs on until its opponent is dead. If facing more than one foe, it won’t employ this tactic so as not to leave itself defenseless against other aggressors. If cornered or extremely hungry, a cavern lizard fights to the death; otherwise, it retreats if facing a particularly powerful opponent.
