Cunning Action. On each of its turns, the thief can use a bonus action to take the Dash, Disengage, or Hide action.

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

Sneak Attack (1/Turn). The thief 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 thief that isn’t incapacitated and the thief doesn’t have disadvantage on the attack roll.
