  • Camouflage. The Rounder can perfectly blend in with ice and snow. The creature has advantage on all stealth checks while in ice or snow.
  • Keen Senses. Due to the rounder’s highly sensitive antennae, the creature has advantage on all perception checks for anything within 30 feet of the creature.
  • Adapted to Ice. The Rounder never suffers penalties to movement for Ice or Snow.


  • Multiattack. The Rounder makes two attacks each round, one with its bite and one with its tail.
  • Bite. Melee Weapon Attack: +4 to hit, reach 10 ft., one target. Hit: 12 (3d6+2) piercing damage. The bite criticals on a 19 or 20, and does triple damage instead of double damage on any critical hit.
  • Tail. Melee Weapon Attack: +4 to hit, reach 10 ft., one target. Hit: 9 (2d6+2) bludgeoning damage.


Ice rounder, or flat head worms, are long, flat creatures that are found in most cold climes. They are generally white or light gray, covered in coarse fur, and are well adapted to hiding in the snowy tundra. Ideally built for travel in the deep snow, the ice rounder is a long creature, growing up to 15 feet in length. They have six thin, long double-jointed legs with webbed toes. They have a broad, flat head, capped by a wide mouth, filled with discordant rows of hundreds of small, thin, razor-sharp teeth. The teeth protrude from the mouth at all angles, even beneath the creature’s thin lips. Their eyes are wide, with huge bluish pupils, but they are nearly blind.

Icy killer. They are stationary hunters, camouflaging themselves in surrounding snow and extending their two whip antennae out and under the snow. These appendages are 6-8 feet long and grow out from beneath the creature’s chin. They resemble thin black whips and are very sensitive to ground movement or heat variations. The ice rounder can tell the size of passing prey as well as its weight and speed. Anything that crosses over its antennae is instantly attacked.

Ravenous. Ice rounders are highly predacious and hunt constantly. They are rarely found in the company of other ice rounders. Their webbed feet allow them to swim, which they do frequently in search of fresh hunting grounds. Their movement is the same in water as out.
