If the spore dragon fails a saving throw, it can choose to succeed instead.
The dragon has advantage on saving throws against spells and other magical effects.
While in sunlight, the dragon has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.
The Dragon can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.
Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 14 (2d6 + 7) piercing damage.
Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) slashing damage.
Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 15 (2d6 + 7) bludgeoning damage.
Each creature of the dragon's choice that is within 120 feet of the Dragon and aware of it must succeed on a DC 17 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.
The Dragon exhales dark spores in a 90-foot cone. Each creature in that area must make a DC 19 Constituion saving throw, taking 54 (12d8) poison damage on a failed save, or half as much on a success.
The dragon makes a Wisdom (Perception) check.
The dragon makes a tail attack.
The dragon beats its wings. Each creature within 10 feet of the storm dragon must succeed on a DC 22 Dexterity saving throw or take 10 (3d6) bludgeoning damage and be knocked prone. The sea dragon can then fly up to half its flying speed.
