  • Multiattack. The giant iguana makes two attacks: one with its bite and one with its tail slap.
  • Bite. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 12 (2d6 + 5) piercing damage.
  • Tail. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 10 (1d10 + 5) bludgeoning damage.


  • Body Shield. Giant iguanas cluster in familial groups for mutual defense. When an adjacent giant iguana is attacked, a giant iguana can use its own body as a reaction to shield and protect its ally, causing that attack to suffer disadvantage.
  • Intimidating Display. When a giant iguana is threatened, as a reaction action it can hiss ferociously, extending its neck dewlap, stiffening its dorsal spines, and puffing up its body in a vicious display. The creature that threatened it, or one creature of its choice within 30 feet (if multiple creatures threatened it), must make a DC 15 Wisdom save or be frightened for 1d6 rounds.


A wide variety of large reptiles can be found inhabiting the torrid zones of the tropics, from the dusty desert sands to the lush jungles and islands.

Giant Gecko. These lizards are mostly docile and shy away from attacking creatures larger than a cat or dog. Despite their shyness, they are ultimately curious creatures, and often approach bigger creatures simply to investigate. Of course, a giant gecko is more than capable of defending itself, biting creatures that react violently to the lizard when fleeing is not an option. Some humanoids train giant geckos as bestial guardians. Smaller humanoids (in particular, goblins) can even use the creatures as mounts, taking advantage of their superior climbing skills to attack from seemingly impossible positions and angles. A giant gecko measures 8 feet from nose to tail and weighs 120 pounds. Coloration among giant geckos can vary wildly, though most are some shade of green.

Giant Horned Lizard. The giant horned lizard is commonly referred to as the blood lizard because of its ability to shoot a stream of blood from its eyes when threatened. The giant horned lizard grows to a length of eight feet.

Giant Iguana. These bright-eyed lizards are larger than horses. They gather in family groups for mutual protection but make elaborate displays of anger to dissuade predators and indicate they are about to charge. When agitated, a brightly dewlap expands like a colored frill around its neck to make it appear larger. Giant iguanas are very agile for their size, able to scale large trees and rocky cliffs, and are equally at home in the water when hunting or migrating.

Giant Beaded Lizard. Giant beaded lizards are predators of the scrublands, similar to their lesser kin in many ways. They are opportunistic hunters that live in areas with rocky structures and at least some plant life. Giant beaded lizards spend the sunlight hours either sleeping in a scratch-dug den, wallowing in a mud puddle or basking in the sun. As the sun begins to go down, they hunt, ranging from their burrows to find prey. Giant beaded lizards are not choosy and will attempt to eat almost anything that can fit in their mouths. When a giant beaded lizard finds something potentially edible, it bites down and does not let go. As it chews, it works venom from its lower jaw into the wound. The venom of a giant beaded lizard is not inherently fatal, but causes swelling, fatigue and excruciating pain. Once a creature succumbs to the venom, the lizard tears it apart and eats it in pieces if it cannot swallow the meal whole. The bite of a giant beaded lizard is so strong that it will not let go even in death.
