Captain Rys, Herald of the Sun

Sun's Blessing. Captain Rys is perpetually bathed in sunlight. Bright light glows in a 30 ft. radius around him, and dim light for an additional 30 ft. Rys and his allies within the bright light radius have advantage on saving throws against spells and magical effects. Additionally, creatures who touch or hit Rys with a melee attack take 20 (4d8) radiant damage.

Radiant Revolver. Rys' revolver is imbued with celestial magic, projecting radiant energy with every bullet. It deals an additional 3d6 radiant damage on a hit. As a bonus action, Rys can overcharge the revolver, making his next shot a critical hit if it hits.

Arcane Mastery. Captain Rys is a 20th-level spellcaster and uses Intelligence as his spellcasting ability (spell save DC 23, +12 to hit with spell attacks). He requires no material components for his spells and can innately cast the following:

At will: Mage Hand, Light, Fire Bolt

3/day each: Disintegrate, Sunbeam, Counterspell

1/day each: Meteor Swarm, Wish

Helldive Strike. Once per day, Captain Rys can leap into the air, transforming into a blazing comet-like explosion. He plummets to a point up to 100 ft. away, causing a 30 ft. radius explosion. Each creature in the radius must succeed on a DC 21 Dexterity saving throw or take 80 (20d6) fire damage and 80 (20d6) radiant damage, or half as much on a successful save.

Multiattack. Captain Rys can make three attacks: two with his Staff of the Sun and one with his Radiant Revolver.

Staff of the Sun. Melee or Ranged Spell Attack: +14 to hit, reach 10 ft. or range 60 ft., one target. Hit: 38 (6d10 + 6) radiant damage. On a critical hit, the target is blinded until the start of Rys' next turn.

Radiant Revolver. Ranged Weapon Attack: +13 to hit, range 60/120 ft., one target. Hit: 28 (4d6 + 8) piercing damage plus 12 (3d6) radiant damage. The attack ignores half and three-quarters cover.

Blazing Counterspell. When Captain Rys successfully counters a spell using Counterspell, he releases a 10 ft. wave of radiant energy. All creatures within the radius must make a DC 21 Constitution saving throw or take 27 (5d10) radiant damage and be pushed 10 ft. away from Rys.

Captain Rys 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. Rys regains spent legendary actions at the start of his turn.

Sunlit Smite. Rys can make one melee or ranged attack with his Staff of the Sun.

Solar Shielding. Rys gains a radiant shield, absorbing up to 40 points of damage for one round. Any remaining absorbed damage when the shield fades is converted into radiant energy and deals damage to the nearest enemy in a 15 ft. radius.

Radiant Pulse (Costs 2 Actions). A beam of pure radiant energy erupts from Rys in a line that is 100 ft. long and 10 ft. wide. Each creature in the line must make a DC 21 Dexterity saving throw or take 66 (12d10) radiant damage, or half as much on a successful save.
