Arcane Trickster (5e Creature)
From D&D Wiki
Medium humanoid (any race), any chaotic alignment
Saving Throws Dex +5, Int +5
Evasion. If the trickster is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, the trickster 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.
