Legendary Resistance (3/Day). If Saiken fails a saving throw, it can choose to succeed instead.
Multiattack. Saiken makes three attacks: one with its advesive spray or corrosive gas, and three with its tails.
Adhesive Spray (recharge 5-6). One creature within 30 ft. must succeed a DC 23 Athletics or Dexterity check or be restrained for 1 minute and take 15 (2d4 + 11) poison damage at the beginning of their turn. They may retry this check at the end of their turn.
Corrosive Gas (recharge 4-6). Every creature within 15 feet must succeed a DC 23 Constitution saving throw or take 17 (2d6 + 11) acid damage.
Tail. Melee Weapon Attack: +18 to hit, reach 20 ft., one target. Hit: 19 (2d8 + 11) bludgeoning damage.
Frightful Presence. Each creature of Saiken choice that is within 120 feet of the dragon and aware of it must succeed on a DC 26 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 the next 24 hours.
Tailed Beast Bomb (recharge 5-6) Saiken 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 26 Dexterity saving throw, taking 66 (10d10 + 7) force damage on a failed save, or half as much damage on a successful one.
Chakra Transfer. Saiken grants another creature 20 temporary hit points.
The Saiken 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 Saiken regains spent legendary actions at the start of its turn.
Tail Attack. Saiken makes a tail attack.
Gather Chakra. Saiken rolls to recharge Tailed Beast Bomb or gains 20 temporary hit points.
Saiken, while speaking boastfully, kinder and not as self-serving and malicious as most other Tailed Beasts. While it generally avoids violence, it does not find it detestable.
