Arcane Trickster (5e Creature)
From D&D Wiki
Medium humanoid (any race), any chaotic alignment
Saving Throws Dex +5, Int +5
Evasion. When the trickster is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.
Sneak Attack (1/Turn). The trickster 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 trickster that isn't incapacitated and the trickster doesn't have disadvantage on the attack roll.
Dagger. Melee or Ranged Weapon Attack: +5 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 5 (1d4 + 3) piercing damage.
Uncanny Dodge. The trickster halves the damage that it takes from an attack that hits it. The trickster must be able to see the attacker.
A coinpurse lifted away by invisible forces, or a searing lethal heat stabbing your back—either is the sign of an arcane trickster. Magical expertise combines with wit and deception to create an unconventional but deadly scoundrel.
