Alansa Tegro, Harlequin

Assassinate. During its first turn, the assassin 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 the assassin 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. Once per turn, the assassin deals an extra 18 (6d6) damage when it hits a target with a weapon attack and has advantage on the attack roll.

Innate Spellcasting: Alansa can cast the following spells (DC 16):

At will: suggestion, enemies abound, invisibility

Multiattack. The assassin makes three Moonstone Blade attacks.

Moonstone Blade. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 5) piercing damage, and the target must make a DC 15 Constitution saving throw, taking 24 (7d6) poison damage on a failed save, or half as much damage on a successful one.

Feyfire. Ranged spell attack: +10 to hit, 90/500 ft., 10 foot area. Hit: 15 (5d6) fire damage. A crature hit by this attack must make a DC 14 dexterity saving throw or be covered in silvery flames that cause the next attack roll against them to have advantage.

Alansa can take 3 legendary reactions per round from the following:

Jester's Laugh (Once per round): Alansa begins laughing maniacally and each hostile creature within 30 feet must make a DC 14 Wisdom Saving throw or laugh uncontrollably until the end of their next turn. This effect makes spells with verbal components impossible to cast. This counts as a charm effect.

Moonlight Dagger: Alansa throws a dagger of moonlight at a creature within 30 ft. +10 to hit, 3d6 Radiant damage. A creature hit by this spell must make a DC 14 Constitution saving throw or have its speed reduced by half until the end of its next turn.

 Cast Spell: Alansa Casts a spell.
