False Identity. You have created a second identity that includes documentation, established acquaintances, and disguises that allow you to assume that persona. Additionally, you can forge documents including official papers and personal letters, as long as you have seen an example of the kind of document or the handwriting you are trying to copy.
Expertise. You have expertise with the Investigation and Stealth skills. Your proficiency bonus is doubled for any ability check you make that uses either of the chosen proficiencies.
Sneak Attack. You know how to strike subtly and exploit a foe's distraction. Once per turn, you can deal an extra 3d6 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack must use a finesse or a ranged weapon.
You don't need advantage on the attack roll if another enemy of the target is within 5 feet of it, that enemy isn't incapacitated, and you don't have disadvantage on the attack roll.
Thieves' Cant. During your rogue training you learned thieves' cant, a secret mix of dialect, jargon, and code that allows you to hide messages in seemingly normal conversation. Only another creature that knows thieves' cant understands such messages. It takes four times longer to convey such a message than it does to speak the same idea plainly.
In addition, you understand a set of secret signs and symbols used to convey short, simple messages, such as whether an area is dangerous or the territory of a thieves' guild, whether loot is nearby, or whether the people in an area are easy marks or will provide a safe house for thieves on the run.
Cunning Action. Your quick thinking and agility allow you to move and act quickly. You can take a bonus action on each of your turns in combat. This action can be used only to take the Dash, Disengage, or Hide action.
Ear for Deceit. You develop a talent for picking out lies. Whenever you make a Wisdom (Insight) check to determine whether a creature is lying, treat a roll of 7 or lower on the d20 as an 8.
Eye for Detail. You can use a bonus action to make a Wisdom (Perception) check to spot a hidden creature or object or to make an Intelligence (Investigation) check to uncover or decipher clues.
Insightful Fighting. You gain the ability to decipher an opponent's tactics and develop a counter to them. As a bonus action, you can make a Wisdom (Insight) check against a creature you can see that isn't incapacitated, contested by the target's Charisma (Deception) check. If you succeed, you can use your Sneak Attack against that target even if you don't have advantage on the attack roll, but not if you have disadvantage on it.
This benefit lasts for 1 minute or until you successfully use this feature against a different target.
Uncanny Dodge. When an attacker that you can see hits you with an attack, you can use your reaction to halve the attack's damage against you.
