Caelia Windwhisper

Fey Ancestry: Caelia has advantage on saving throws against being charmed, and magic can't put her to sleep. 

Evasion: If Caelia is subjected to an effect that allows her to make a DEX saving throw to take only half damage, she instead takes no damage if she succeeds on the saving throw, and only half damage if she fails.

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

Spellcasting: Caelia is a 5th-level spellcaster. Her spellcasting ability is Charisma (spell save DC 14, +6 to hit with spell attacks). She knows the following bard spells: 

Cantrips (at will): message, minor illusion, mage hand

1st level (4 slots): disguise self, cure wounds, silent image
2nd level (3 slots): invisibility, mirror image
3rd level (2 slots): dispel magic, major image

Multiattack: Caelia makes two shortsword attacks.

Shortsword: Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) piercing damage.

Shortbow: Ranged Weapon Attack: +7 to hit, range 80/320 ft., one target. Hit: 7 (1d6 + 4) piercing damage.

Uncanny Dodge: When an attacker Caelia can see hits her with an attack, she can use her reaction to halve the attack's damage against her.
