Quick Reference
Running This Encounter
The mammoth is a straightforward melee combatant that charges at threats with its tusks and tramples with its weight. Position it in open terrain where its 40 ft. movement speed is advantageous, and use its Trampling Charge (DC 18 STR save, 3d8+5 damage) as a primary action against clustered foes. Don't separate the mammoth from its herd if multiple creatures are present, as they'll coordinate attacks. Keep the creature mobile rather than letting it be surrounded.
Combat Tactics
The mammoth charges its most dangerous-looking opponent each turn, prioritizing spellcasters if they're visible. It uses its Gore attack against one target and its Trampling Charge when three or more enemies cluster together. The mammoth fights to the death if defending calves or herd mates; otherwise it may flee if reduced below 25 HP.
Environment & Setting
Open grasslands, tundra, or taiga where large herds roam freely and provide natural cover. Ideal if there are rocky outcroppings, frozen terrain features, or water sources that create dynamic movement challenges.
