Channel Radiation. When the dragon uses its action to Channel Life, it can instead release a wave of radiation. Creatures other than the dragon within the corona must make a DC 18 Constitution save, taking 10 (3d6) radiant damage and 10 (3d6) poison damage. Constructs are immune to this ability. Intergalactic. In outer space, the dragon can survive in the void and fly at incredible speed. Travel times vary, but a trip within a single solar system should take 3d20 hours, and a trip beyond should take 3d20 days or more if the dragon knows the way to its destination. The dragon can carry one rider of one size category smaller than itself, four passengers two sizes smaller, eight passengers three sizes smaller, or 16 passengers four or more sizes smaller. Passengers are protected from the void of outer space. Primal Fire. The dragon’s breath weapon ignores a target’s resistance to fire; targets who are immune to fire instead only resist the dragon’s breath weapon.
Actions
Multiattack. The dragon can use its Alien Presence. It then makes three attacks: one with its bite and two with its claws. Bite. Melee Weapon Attack: +14 to hit, reach 15 ft., one target. Hit: 19 (2d10 + 8) piercing damage plus 9 (2d8) fire damage. Claw. Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 15 (2d6 + 8) slashing damage. Tail. Melee Weapon Attack: +14 to hit, reach 20 ft., one target. Hit: 17 (2d8 + 8) bludgeoning damage. Alien Presence. Each creature of the dragon’s choice that is within 120 feet of the dragon and can see it must succeed on a DC 22 Wisdom saving throw or become blinded for 1 minute. An affected 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 Alien Presence for the next 24 hours. Solar Breath (Recharge 5–6). The dragon exhales a solar flare in a 120-foot line that is 10 feet wide. Each creature in that line must make a DC 20 Dexterity saving throw, taking 31 (9d6) radiant damage and 31 (9d6) fire damage on a failed save, or half as much damage on a successful one. Channel Life (3/Day). The dragon creates a corona of sunlight in a 90-foot radius centered on the dragon. All living creatures within the corona regain 31 (7d8) hit points. Undead within the corona must make a DC 18 Constitution saving throw or take an equal amount of radiant damage and become blinded for 1 minute. On a successful save, an undead creature takes half as much damage and isn’t blinded.
Legendary Actions
The dragon 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 solar dragon regains spent legendary actions at the start of its turn. Detect. The solar dragon makes a Wisdom (Perception) check. Tail Attack. The solar dragon makes a tail attack. Wing Attack (Costs 2 Actions). The dragon beats its wings. Each creature within 15 feet of the dragon must succeed on a DC 22 Dexterity saving throw or take 15 (2d6 + 8) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed.
Lair Actions
- On initiative count 20 (losing initiative ties), a solar dragon takes a lair action to cause one of the following effects; the dragon can’t use the same effect two rounds in a row:
- A searing beam of light strikes a creature within 120 feet of the dragon that it can see. The dragon makes one ranged attack roll (+6 to hit) against the target. On a hit, the target takes 3 (1d6) radiant damage and 3 (1d6) fire damage and is blinded until the end of its next turn.
- A solar wind rushes through the lair in a 90-foot line that is 15-feet wide originating from a point within 120 feet of the dragon that it can see. Each creature in the solar wind’s area must succeed a DC 15 Strength saving throw or be pushed 15 feet following the direction of the line and take 3 (1d6) radiant and 3 (1d6) fire damage on a failed save, or half as much damage and isn’t pushed on a successful one. The solar wind disperses gas or vapors.
- The moisture in the air rapidly dries out in a 60-foot radius centered on the dragon. Each creature within the area is overcome with an unquenchable thirst and must make a DC 15 Constitution saving throw, suffering a level of exhaustion on a failed save. Constructs and creatures immune to fire damage are immune to this ability.
