Captain Roki, Herald of The Moon

Legendary Resistance (3/Day). If Roki fails a saving throw, he can choose to succeed instead.

Lunar Vision. Roki has superior vision, able to see normally in any form of darkness, whether magical or mundane.

Moonlit Shroud. A swirling cloak of moonlight enfolds Roki, granting him an AC bonus of +2 and resistance to necrotic and radiant damage. In dim light or darkness, this cloak also makes all attacks against him at disadvantage.

Helldiver's Gambit. When Roki successfully deals damage with his revolver or dagger, he can choose to deal an additional 40 radiant damage once per turn. Roki has 4 uses of this feature. He also regains 10 hit points whenever he reduces a creature to 0 hit points using this ability.

Innate Spellcasting. Roki's innate spellcasting ability is Charisma (spell save DC 20, +12 to hit with spell attacks). He can innately cast the following spells without material components:

At will: Misty Step, Silence, Moonbeam

3/day each: Greater Invisibility, Dimension Door

1/day each: Mass Suggestion, Heal

Multiattack. Roki can make three attacks: two with his Lunar Dagger and one with his Moonbound Revolver.

Lunar Dagger. Melee Weapon Attack: +16 to hit, reach 5 ft., one target. Hit: 26 (4d6 + 12) piercing damage plus 16 (3d10) radiant damage. If the target is a creature, it must succeed on a DC 22 Constitution saving throw or be blinded for 1 minute. The creature can use an action on its turn to repeat the save.

Moonbound Revolver. Ranged Weapon Attack: +16 to hit, range 50/150 ft., one target. Hit: 32 (6d6 + 10) piercing damage plus 20 (4d6) radiant damage. The revolver never runs out of ammunition, as Roki loads it with pure lunar essence.

Night's Cloak (1/day). As an action, Roki becomes invisible for 1 minute. During this time, his revolver and dagger attacks deal additional 25 necrotic damage, and his movement leaves no trace. The invisibility ends early if he drops to 0 hp.

Shadowstep. As a bonus action, Roki can teleport up to 60 feet to an unoccupied space within dim light or darkness. He can then make a melee attack with advantage against a creature within 5 feet of the destination.

Rogue's Cunning. Roki can take both the Dash and Disengage action as a bonus action. Additionally, he cannot be caught flat-footed, and attacks made against him do not benefit from advantage even if he is surprised.

Roki 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. Roki regains spent legendary actions at the start of his turn.

Shadowstrike. Roki makes one Lunar Dagger attack from the shadows, ignoring resistance to radiant damage.

Moonlit Dodge. Roki moves up to half his speed without provoking opportunity attacks, teleporting into dim light or darkness if available.

Lunar Pulse (Costs 2 Actions). Roki releases a pulse of concentrated lunar energy. Each creature of his choice within 30 ft. must succeed on a DC 22 Dexterity saving throw or take 60 (12d10) radiant damage and be knocked prone. Creatures in dim light or darkness have disadvantage on this save.
