Blighted Green Dragon

Amphibious. The Blighted Green Dragon can breathe air and water.

Hive Mind. The Blighted Green Dragon shares a hive mentality with other Blighted creatures, allowing them to act in unison. If one Blighted creature is aware of a hostile creature, all others in the hive mind are also aware.

Blighted Scourge. Natural weapon attacks by the Blighted Green Dragon carry the Blighted Scourge infection. A creature hit by the dragon’s attacks must succeed on a DC 16 Constitution saving throw or contract the Blighted Scourge.

Multiattack. The Blighted Green Dragon can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.

Bite. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 17 (2d10 + 6) piercing damage plus 7 (2d6) poison damage. The target must succeed on a DC 16 Constitution saving throw or contract the Blighted Scourge.

Claw. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 7 (2d4 + 6) slashing damage.

Tail. Melee Weapon Attack: +9 to hit, reach 15 ft., one target. Hit: 10 (2d6 + 6) bludgeoning damage.

Frightful Presence. Each creature of the dragon's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 16 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 the dragon’s Frightful Presence for the next 24 hours.

Blight Breath (Recharge 5-6). The Blighted Green Dragon exhales a cone of blighted energy in a 45-foot cone. Each creature in that area must make a DC 16 Constitution saving throw, taking 36 (8d8) blighted energy damage on a failed save or half as much on a successful one. Creatures that fail the saving throw also advance one stage in the Blighted Scourge infection.

Poison Breath (Recharge 5-6). The Blighted Green Dragon exhales poisonous gas in a 45-foot cone. Each creature in that area must make a DC 16 Constitution saving throw, taking 45 (13d6) poison damage on a failed save or half as much damage on a successful one. Creatures that fail the saving throw advance one stage in the Blighted Scourge infection.
