Enma (Shinobi World Supplement)
From D&D Wiki
Monkey King Enma
Medium humanoid (Monkey), lawful neutral
Saving Throws Con +7, Int +5
Chakra. Enma has 25 chakra points which he can expend. All chakra points are regained at the end of a long rest.
Endurance. When Enma is targeted by an area effect that lets him make a Dexterity saving throw to take only half damage, such as fireball, he instead takes no damage if he succeeds on the saving throw, and only half damage if he fails the save.
Ninja Speed. Enma can take the dash, dodge, and disengage actions as a bonus action, and can move along vertical surfaces.
Multiattack. Enma can make 3 unarmed strikes.
Unarmed Strike. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 13 (4d4 + 5) magical bludgeoning damage.
Kunai. Thrown Weapon Attack: +8 to hit, range 30/60 ft., one target. Hit: 6 (1d4 + 4) piercing damage. Enma may spend up to 3 chakra when he takes this action, making one additional attack per chakra point spent. Each additional kunai deals 3 (1d4 + 1) piercing damage on a hit.
Transformation: Adamantine Staff (5 Chakra). Enma becomes a simple, two-handed, finesse weapon taking the form of a thick staff. Any creature wielding it can make attacks with it, gaining a +1 bonus to attack and damage rolls, an additional 15 ft. of reach, and dealing 4d4 magical bludgeoning damage on a hit. Enma can spend his action in this form to end this effect, or increase this weapon's reach by +5 ft. until the beginning of his next turn for 2 chakra, or use Adamantine Prison Wall, and he can not take other actions or move.
Adamantine Prison Wall (5 Chakra). While Transformation: Adamantine Staff is active, Enma becomes a 30 ft. hollow cube centered on where the staff was. Creatures can see and hear through this cube, and Tiny creatures can pass through its walls. It has Enma's hit points and AC, and is resistant to bludgeoning, slashing, and piercing damage.
As his name implies, Enma is the King of Monkeys, though his exact place of residence is unknown. At some point, Hiruzen Sarutobi met with Enma, forming a contract with him. Enma acted as a secondary advisor to Hiruzen, being very loyal and defensive of him disapproving of his soft governing, and is very defensive of his old friend. Enma has not been seen since Hiruzen's death. Having look relatively similar when they met in Hiruzen's prime to his death, it's very likely that Enma is older than the hidden village system itself.
