Actions

Headbutt. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 11 (2d8 + 2) bludgeoning damage.

Tail Sweep. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) bludgeoning damage, and the target must succeed on a DC 13 Strength saving throw or be knocked prone.

Ramming Charge (1/day). The creature charges forward and rams into its target, dealing 16 (3d10) bludgeoning damage and knocking the target prone. The target must succeed on a DC 13 Dexterity saving throw or take an additional 7 (2d6) bludgeoning damage from falling debris.

Stampede (1/day). Prenocephale and up to two other Prenocephales can use this action if they are within 30 feet of each other. Each one charges forward in a straight line and tramples any creature in its path. Each creature in the path of the stampede must make a DC 13 Dexterity saving throw, taking 11 (2d10) bludgeoning damage on a failed save, or half as much damage on a successful one.

Abilities

Charge. If Prenocephale moves at least 20 feet straight toward a target and then hits it with a headbutt attack on the same turn, the target takes an extra 9 (2d8) bludgeoning damage.

Pack Tactics. Prenocephale has advantage on attack rolls against a creature if at least one of its allies is within 5 feet of the creature and the ally isn’t incapacitated.

Stubborn. Once Prenocephale has chosen a target, it does not stop its attack until either the target or itself is defeated.

Lair Actions

Prenocephale’s lair is typically an area with dense foliage or rocky terrain that allows them to hide and ambush prey. Whenever a creature enters the lair, the following lair actions can be taken in initiative order:

1. Camouflage. They can spend a lair action to hide in natural terrain, gaining advantage on Dexterity (Stealth) checks until it moves or takes an action.
2. Ambush. They can spend a lair action to charge and headbutt a target that it had previously hidden from, gaining advantage on the attack roll.
3. Terrain Disruption. The creatures can spend a lair action to create difficult terrain by knocking over boulders or felling trees.
