Saving Throws Str +16, Con +15, Wis +11, Cha +11
Legendary Resistance (3/Day). If Isobu fails a saving throw, it can choose to succeed instead.
Chakra Constitution. Isobu has advantage on saving throws against spells and other magical effects. Isobu’s attacks are considered magical.
Multiattack. Isobu makes 3 claw attacks, a bite attack, and a tail attack.
Bite. Melee Weapon Attack: +16 to hit, reach 10 ft., one target. Hit: 25 (3d10 + 9) piercing damage.
Claw. Melee Weapon Attack: +16 to hit, reach 10 ft., one target. Hit: 16 (2d6 + 9) slashing damage.
Tail. Melee Weapon Attack: +16 to hit, reach 20 ft., one target. Hit: 18 (2d8 + 9) bludgeoning damage.
Coral Creation. Isobu chooses a 10 ft. cube within 120 feet. This area becomes difficult terrain for 1 hour unless it is underwater, in which it is permanent. If this area is already difficult terrain, it becomes impassible. This Coral has the same hit points and AC as wood.
Frightful Presence. Each creature of Isobu’s choice that is within 120 feet of and aware of it must make a DC 19 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to Frightful Presence for 24 hours.
Tailed Beast Bomb (Recharge 5-6). Isobu chooses a space within 120 feet and fires a 60 foot sphere of chakra centered on that point. Every creature within range must succeed a DC 23 Dexterity saving throw, taking 61 (10d10 + 2) force damage on a failed save, or half as much damage on a successful one.
Chakra Transfer. Isobu grants another creature 20 temporary hit points.
The Isobu can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The Isobu regains spent legendary actions at the start of its turn.
Gather Chakra. Isobu rolls to recharge Tailed Beast Bomb or gains 20 temporary hit points.
Tail. Isobu makes a Tail attack.
Harden. Isobu gains +2 AC until the beginning of its next turn.
Isobu, the third weakest of the Tailed Beasts, often acts in a timid manner. It isn't as rude or outspoken as some of the other Tailed Beasts and is generally amicable, if reclusive, to others.
