Special Traits


  • Bite. Melee Weapon Attack: +5 to hit, reach 10 ft., one target. Hit: 10 (2d6 + 3) piercing damage. If the target is a creature it must succeed on a DC 13 Constitution saving throw or be diseased until the condition is cured. While the creature is diseased it is poisoned.. Every 24 hours that elapse, the target must repeat the saving throw, reducing its hit point maximum by 5 (1d10) on a failure. The disease is cured on a success. The target dies if the disease reduces its hit point maximum to 0. This reduction to the target’s hit point maximum lasts until the disease is cured.


Bristling with coarse hairs, this enormous fly’s legs twitch just before it launches into the air on buzzing wings. This human-sized insect has large, red, globular eyes, a body covered in hairy bristles, and two rapidly vibrating translucent wings.

Giant flies are larger relatives of normal flies. Like their lesser cousins, they are most often found in areas of garbage, litter, and refuse. A giant fly resembles a normal fly and can grow to a length of 12 feet, though most average about 6 feet long.

Giant flies attack by biting their opponents.
