Monkey Rock (Shinobi World Supplement)
From D&D Wiki
Huge construct, unaligned
Saving Throws Dex +11, Con +11
Endurance. When the monkey rock is targeted by an area effect that lets it make a Constitution saving throw to take only half damage, such as fireball, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails the save.
Ninja Speed. The monkey rock can take the dash, dodge, and disengage actions as a bonus action, and can move along vertical surfaces.
Unliving. The monkey rock is not alive in its own right. One creature within 90 feet capable of using Monkey Rock jutsu must control it until the beginning of their next turn as an action for 1 chakra. If two creatures attempt to control it, the second creature must attempt a Constitution saving throw with a DC equal to the first creature's jutsu saving throw DC, controlling it on a success. If the monkey rock is not being controlled, it is unconscious.
Chakra Conduit. The chakra costs of the monkey rock's actions must be fulfilled by the creature controlling it, and any saving throws they incur have a DC equal to their controller's jutsu saving throw DC.
Immutable Form. The monkey rock is immune to any spell or effect that would alter its form.
Magic Resistance. The monkey rock has advantage on saving throws against spells and other magical effects.
Magic Weapons. The monkey rock's weapon attacks count as magical for the sake of overcoming resistances.
Multiattack. The monkey rock can make 3 unarmed strikes.
Unarmed Strike. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 12 (5d4 + 3) bludgeoning damage.
Body Flicker (2 Chakra). The monkey rock's movement speed doubles, and his movement does not provoke attacks of opportunity.
Flame Enhancement (8 Chakra). The monkey rock's stony surface glows brightly with fire. Its unarmed strikes deal fire damage, and creatures that hit it with an unarmed strike or end their turn while grappling or being grappled by the monkey rock take 5 fire damage. The controller must spend 1 chakra at the end of each of their turns to maintain this effect. The controller must be able to use Fire Style to use this action.
Earth Style Amplification (5+ Chakra). The monkey rock regains twice as many hit points as chakra points spent.
Self Destruct (10 Chakra). All creatures in a 30 foot radius must attempt a Dexterity saving throw. On a failure, they take 23 (4d8 + 5) magical bludgeoning damage and are pushed 30 ft. away from the monkey rock. On a success, they take half as much damage and are moved half as far. This feature ignores Evasion. After using this action, the monkey rock immediately drops to 0 hit points.
First seen being used by Momoshiki Otsutsuki, though likely originating from one of the numerous individuals he had stolen power from in the past, the monkey rock is capable of facing down tailed beasts, and even holding off Naruto and Sasuke's combined power for an extended fight. In many ways, it can be considered one of the pinnacles of Earth Style, and its Fire Style-enhanced form could even be considered a pseudo-Explosive Style jutsu.
