  • Siege Monster. The undead mammoth does double damage to objects and structures.
  • Trampling Charge. If the undead mammoth 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 17 Strength saving throw or be forced prone.
  • Undead Fortitude. If damage reduces the undead mammoth to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the undead mammoth drops to 1 hit point instead.


  • Gore. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 20 (3d8 + 7) piercing damage plus 3 (1d6) necrotic damage.
  • Stomp. Melee Weapon Attack: +10 to hit, reach 5 ft., one prone creature. Hit: 23 (3d10 + 7) bludgeoning damage.


Enormous shadows can be seen moving through a foggy pass. Then several huge, dark mammoths begin to emerge from the mist. These undead mammoths are the result of dark magic that came through Riftgates. Necrotic energy that entered this region twists the souls of some mammoths when they die.

Hulking Horror. The vothdar will use these undead creatures as pack animals. Their necromancers, the blizzard wizards, can command the sizable creatures to do their bidding. However, the undead horrors can only take simple directions from the snow elves.

Herd Immunity. Undead mammoths usually stick together in groups. The region is a very dangerous place, and they will try to remain in their herd. Since they can see in the dark and don’t have the requirements of living creatures, some herds can be seen on the move in the middle of the night.

Undead Nature. An undead mammoth doesn’t require air, food, drink, or sleep.
