If you’ve played around extensively with dragons, not a lot in the lunar dragon or solar dragon stat blocks will come as a surprise. At every life stage, they share the archetypal Strength-and-Constitution-heavy brute ability contour of most chromatic and metallic dragons, along with breath weapons and proficiency in the ambush skills (Perception and Stealth). Young, adult and ancient lunar dragons possess the classic Claw/Claw/Bite Multiattack, while solar dragons, which lack claws, attack in the same manner but with Bite and Tail; adult and ancient lunar and solar dragons have Legendary Resistance, and ancient lunar dragons have opportunistic Tail attacks along with Wing Attacks for when more opponents than they’d prefer are engaging them in melee and they want to bug out.
So let’s focus on what makes them different. Lunar dragons, which typically dwell in burrows on (wait for it) barren moons, aren’t all that different from white dragons; power-wise, they’re on par or very slightly weaker. They lack blindsight, but their darkvision has much greater range: 120 feet for wyrmlings, 240 feet after they hit puberty. This fact suggests that they dig big: When they burrow into a moon, they carve out not only tunnel networks (although those would be great for trespassers to get lost in) but also an enormous central cavern with plenty of room to maneuver in and no illumination whatsoever. Their Cold Breath deals less damage than a white dragon’s, but it also immobilizes targets that fail their saving throws. Those targets aren’t restrained or paralyzed, so freezing them doesn’t grant the dragon advantage on its follow-up attack rolls, but it does prevent them from pursuing (if they’re trying to engage in melee with the dragon) or from escaping (if they’re trying to avoid engagement).(more…)
