Special Traits

  • Keen Smell. The mammoth has advantage on Wisdom (Perception) checks that rely on smell.
  • Charge. If the 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 knocked prone. If the target is prone, the mammoth can make one stomp attack against it as a bonus action.

  • Gore. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 16 (3d6 + 6) piercing damage.
  • Slam. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 15 (2d8 + 6) bludgeoning damage.

This massive elephant-like creature is covered in long, coarse hair, and its tusks sweep upward in great curves of yellowed ivory.

The woolly mammoth is a relative of both the common elephant and the mastodon. Like the mastodon, it is an herbivore and spends its days eating nuts, fruits, berries, and grasses. The typical mammoth consumes nearly 450 pounds of food and 50 gallons of water in a given day.

Mammoths travel in herds with the young moving in the center, protected and surrounded by the adults. If danger is present or a threat is imminent, the males move to face the danger, while the females encircle the young.

The woolly mammoth generally reproduces in the spring months with young being born about 22 months later. A young woolly mammoth resembles a miniature version of an adult, complete with fur, and underfur. It does not yet have the mighty tusks of the mammoth, though the tusks grow in quickly as the young mammoth reaches maturity (around age 12).

The mammoth has the same predators as the mastodon; the dire wolf, the smilodon, and man. Man hunts these creatures for the same reason they hunt the mastodon: meat, fur, ivory, or to capture young mammoths to be trained as mounts and beasts of burden.

The mammoth is a relative of the elephant and the mastodon though its head is slightly taller than an elephant’s and slightly wider than a mastodon’s. Its upward curving tusks are longer than those of the mastodon, and its trunk ends in two, small finger-like projections used for grasping branches, fruits, and other such small items. The mammoth stands about 22 feet tall and is covered in a thick coat of gray, brown, reddish-brown, yellowish-brown, or black fur with a coarse “under-fur” beneath it to protect it in harsh climates.

Mammoths generally avoid combat unless provoked or the herd is threatened. They have no natural fear of any creature, so do not flee. If the herd is threatened, mammoths fight by goring with their tusks or trampling. Mammoths fight to the death to protect their young.
