Ear to the Ground
You are in frequent contact with people in the segment of society that your chosen quarries move through. These people might be associated with the criminal underworld, the rough-and-tumble folk of the streets, or members of high society. This connection comes in the form of a contact in any city you visit, a person who provides information about the people and places of the local area.

Sneak Attack
Beginning at 1st level, you know how to strike subtly and exploit a foe's distraction. Once per turn, you can deal an extra 1d6 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.

The amount of the extra damage increases as you gain levels in this class, as shown in the Sneak Attack column of the Rogue table.

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
Starting at 2nd level, 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.

Steady Aim
At 3rd level, as a bonus action, you give yourself advantage on your next attack roll on the current turn. You can use this bonus action only if you haven't moved during this turn, and after you use the bonus action, your speed is 0 until the end of the current turn.

Moderately Armored
Prerequisite: Proficiency with light armor
You have trained to master the use of medium armor and shields, gaining the following benefits:
Increase your Strength or Dexterity score by 1, to a maximum of 20.
You gain proficiency with medium armor and shields

Fancy Footwork
When you choose this archetype at 3rd level, you learn how to land a strike and then slip away without reprisal. During your turn, if you make a melee attack against a creature, that creature can't make opportunity attacks against you for the rest of your turn.

Rakish Audacity
Starting at 3rd level, your confidence propels you into battle. You can give yourself a bonus to your initiative rolls equal to your Charisma modifier.

You also gain an additional way to use your Sneak Attack; you don't need advantage on the attack roll to use your Sneak Attack against a creature if you are within 5 feet of it, no other creatures are within 5 feet of you, and you don't have disadvantage on the attack roll. All the other rules for Sneak Attack still apply to you.

Gift of the Gem Dragon
You’ve manifested some of the power of gem dragons, granting you the following benefits:
Ability Score Increase. Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
Telekinetic Reprisal. When you take damage from a creature that is within 10 feet of you, you can use your reaction to emanate telekinetic energy. The creature that dealt damage to you must make a Strength saving throw (DC equals 8 + your proficiency bonus + the ability modifier of the score increased by this feat). On a failed save, the creature takes 2d8 force damage and is pushed up to 10 feet away from you. On a successful save, the creature takes half as much damage and isn’t pushed. You can use this reaction a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest
