Mountain Oni - AI-generated fantasy Monster

Mountain Oni

Old mountain folk tell of crimson giants who were once protectors and then became hungrier for blood when offerings stopped. Travelers leave small coins and rice at passes to appease them. Seeing one is said to presage avalanches or the uncovering of an ancient curse.

Magic Resistance. The oni has advantage on saving throws against spells and other magical effects.
Regeneration. At the start of its turn, the oni regains 10 hit points if it has at least 1 hit point. If the oni takes fire damage, its regeneration is suppressed until the start of its next turn.
Intimidating Presence. The oni is a hulking presence. Creatures that start their turn within 5 feet of the oni have disadvantage on ability checks to hide.
Multiattack. The mountain oni makes two melee attacks: one with its kanabō and one with its claw. If both attacks hit the same target, the target must succeed on a Strength saving throw or be knocked prone.
Kanabō. Melee Weapon Attack: to hit, reach 5 ft., one target. Hit: 15 () bludgeoning damage. On a critical hit, the target is also pushed 10 feet away.
Claw. Melee Weapon Attack: to hit, reach 5 ft., one target. Hit: 9 () slashing damage.
Rock-Thrown Javelin. Ranged Weapon Attack: to hit, range 30/120 ft., one target. Hit: 8 () piercing damage. A target hit by the javelin while within 5 feet of the oni is dealt an additional 4 () piercing damage.
Enfeebling Roar (Recharge 5-6). The oni releases a booming, animal-like roar. Each creature of the oni's choice within 30 feet that can hear it must succeed on a Wisdom saving throw or become frightened of the oni for 1 minute. A frightened target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. On a successful save, a target is immune to the same oni's Roar for 24 hours.
Groundquake. The oni sweeps the ground with a thunderous strike. All creatures in a 15-foot cone must make a Dexterity saving throw, taking 18 () bludgeoning damage on a failed save, or half as much on a successful one. Creatures that fail are knocked prone.
Fierce Interpose. When a creature the oni can see within 5 feet attacks an ally of the oni, the oni can use its reaction to make one claw attack against the attacker.
