Mountain Strider 2014
CR 1 monstrosity
Large monstrosity, chaotic neutral
If the mountain strider moves at least 15 feet straight toward a target and then hits it with a headbutt attack on the same turn, the target takes an extra 5 (2d4) bludgeoning damage. If the target is a creature, it must succeed on a DC 13 Strength saving throw or be pushed up to 10 feet away from the mountain strider and knocked prone.
The mountain strider has advantage on Strength and Dexterity saving throws made against effects that would knock it prone.
Actions
Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (2d4 + 3) bludgeoning damage.
Melee or Ranged Weapon Attack: +5 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 6 (1d6 + 3) piercing damage, or 7 (1d8 + 3) piercing damage if used with two hands to make a melee attack.
The mountain strider releases a loud bleat in a 15-foot cone. Each creature in the area must make a DC 13 Dexterity saving throw, taking 7 (2d6) thunder damage on a failed save, or half as much damage on a successful one.
Reactions
When an ally the mountain strider can see is reduced to 0 hp within 30 feet of the mountain strider, the strider can move up to half its speed and make a headbutt attack.
