Traits

Assassinate. During its first turn, Kinyel has advantage on attack rolls against any creature that hasn't taken a turn. Any hit the assassin scores against a surprised creature is a critical hit.

Evasion. If Kinyel is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, the assassin instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.

Sneak Attack (1/Turn). Kinyel deals an extra 14 (4d6) damage when it hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of the assassin that isn't incapacitated and the assassin doesn't have disadvantage on the attack roll.

Fey Ancestry. <$title_short_name$> has advantage on saving throws against being charmed, and magic can't put <$short_name$> to sleep.

Sunlight Sensitivity. While in sunlight, <$short_name$> has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

Spellcasting

Innate Spellcasting. <$title_short_name$>'s innate spellcasting ability is Charisma (spell save DC <$spell_dc__cha$>). <$title_short_name$> can innately cast the following spells, requiring no material components:
