Actions

Tail. Melee Weapon Attack: +7 to hit, 1d20+7 reach 10 ft., one target. Hit: 26 5d8+4 bludgeoning damage. If the target is a creature, it must succeed on a DC 16 Strength saving throw or be knocked prone.   Ram. Melee Weapon Attack: +7 to hit, 1d20+7 reach 5 ft., one target. Hit: 11 2d6+4 bludgeoning damage. If the target is a creature, it must succeed on a DC 16 Strength saving throw or be shoved 5 ft. directly away and knocked prone.   Entrench. The ankylosaurus readies itself for combat, reducing its movement speed to 5 ft. and enabling the use of the Defensive Stance reaction. This effect lasts until it is shoved more than 5 ft., knocked prone, or it chooses to end it at the start of its turn.

Reactions

Defensive Stance. While the ankylosaurus is Entrenched, when a creature within 5 feet hits it with a melee attack, it makes a Ram attack against that creature.
