Special Traits

  • Keen Smell. The Elasmotherium has advantage on Wisdom (Perception) checks that rely on smell.
  • Siege Monster. The Elasmotherium deals double damage to objects and structures.
  • Trample. If the Elasmotherium moves at least 20 feet straight toward a creature and then hits it with a gore attack on the same turn, that target must succeed on a DC 18 Strength saving throw or be knocked prone. If the target is prone, the Elasmotherium can make stomp on the target as a bonus action.


  • Gore. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 43 (10d6 + 8) piercing damage.
  • Stomp. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 34 (4d12 + 8) bludgeoning damage and the target must succeed on a DC 17 Constitution saving throw or be stunned for 1 minute. The stunned creature can repeat the saving throw on each of its turns, ending the effect on a success.


This creature has massive legs and a stout body with a thick coat of brown fur. Two curving horns rise from the tip of its elongated nose.

A giant beast grazes peacefully with its herd. But be careful, for these creatures are highly territorial, and will attack if you enter their domain. If something threatens the herd, the females will circle the young, while the males will seek out the intruders. They have been known to sweep riders from their horses with their horn and toss them into the air repeatedly until the rider is killed.

Ancient tales describe the Elasmotherium as an intelligent beast, able to distinguish right from wrong, and representations of it were placed in courtrooms and on the caps of judges. In northern lands, a white Elasmotherium was considered to be an omen of a harsh winter.

Distinguished by a massive horn on its head, the Elasmotherium is the size of a mammoth and covered in a grey-brown fur. Long legs allow Elasmotherium to gallop like a horse, charging full-speed at its enemies in order to gore them with its horn. The horn is used for defense of its territory and mates, and for driving away competitors in their grazing grounds.

The Elasmotherium stands 7-feet tall at the shoulder and reaches lengths of up to 16-feet long. At a weight of 10,000 pounds, this massive beast packs a powerful punch when it charges. The horn can reach lengths of 5 feet and is made of hardened keratin, rather than bone. The tip of the horn forms a sharp point, easily penetrating the defenses of unwary enemies.
