Traits

Aura of the Noon Sun. Ra sheds bright light in a 120-foot radius and dim light for an additional 120 feet. Any creature that starts its turn within the bright light must succeed on a DC 24 Constitution saving throw or be blinded until the start of its next turn.
Magic Resistance. Ra has advantage on saving throws against spells and other magical effects.
Solar Form. Ra can move through a space as narrow as 1 inch wide without squeezing. Any creature that touches Ra or hits him with a melee attack while within 5 feet of him takes 21 (6d6) radiant damage.
Legendary Resistance. If Ra fails a saving throw, he can choose to succeed instead.

Morning Glory. Ra sheds bright light in a 60-foot radius and dim light for an additional 60 feet. Each hostile creature that starts its turn in the bright light must succeed on a DC 25 Constitution saving throw or take 21 (6d6) radiant damage.

Solar Flare Retaliation. When a creature hits Ra with an attack, Ra can force the attacker to make a DC 25 Dexterity saving throw. On a failure, the attacker takes 28 (8d6) fire damage and is pushed 20 feet away.

Mirage of the Sands. The air in the lair shimmers, creating illusory duplicates of Ra. Until initiative count 20 on the next round, attack rolls against Ra have disadvantage.
Solar Zenith. A pillar of concentrated sunlight strikes a point Ra can see within 120 feet. Each creature in a 10-foot-radius, 40-foot-high cylinder centered on that point must make a DC 24 Dexterity saving throw, taking 44 (8d10) radiant damage on a failed save, or half as much on a successful one.

Eternal Noon. Within 6 miles of the lair, the sun never sets, remaining at a constant, blistering zenith, causing plants to grow at an accelerated rate but turning soil to cracked, dry earth.
Golden Radiance. Beasts and humanoids within 6 miles of the lair feel an overwhelming sense of order and authority, making them incapable of acts of stealth or deception while under the open sky.
Solar Omen. Any bird of prey within 6 miles of the lair behaves as if it were an extension of Ra’s will, watching the party and occasionally diving to mark their location with a screech of pure light.
