Your quick reflexes and agility let you take a bonus action on each of your turns in combat. This action can be used only to Dash, Disengage, or Hide.

You are a faster, more versatile burglar. You can use the bonus action from Cunning Action to make a Dexterity (Sleight of Hand) check, use thieves' tools to disarm a trap or open a lock, or take the Use an Object action.

When a creature hits you with an attack, you can use your reaction to halve the damage from that attack.

You can use your reaction to take no damage on a successful Dexterity saving throw against effects that would normally deal half damage on a success, and only half damage on a failure.

You have learned to focus your training on a few skills, doubling your proficiency bonus for two chosen proficiencies. You gain additional Expertise choices at 6th level.

You know how to strike subtly and exploit a foe's distraction. Once per turn, you can deal an extra 5d6 damage to one creature you hit with an attack if you have advantage on the attack roll, or if another enemy of the target is within 5 feet of it and you do not have disadvantage.

You can speak, read, and write a secret mix of dialect, jargon, and code used by rogues and criminals.

You are an expert at climbing, jumping, and moving through the world of ledges, roofs, and broken terrain. Your climbing speed increases, and you can use a running start to jump farther.

At 4th level, and again at 8th level, you have improved your abilities. This character has used both improvements to sharpen Dexterity and keep pace with the life of a knife-edge outlaw.

Your knack for avoiding detection is unparalleled. If you move no more than half your speed on your turn, you do not suffer disadvantage on Dexterity (Stealth) checks from moving at a normal pace, and creatures have disadvantage on Wisdom (Perception) checks to spot you while you are moving.

You become even better at a chosen set of skills or tools, gaining Expertise in two additional proficiencies.

You have a reliable contact who acts as your connection to a network of other criminals. This contact can provide information, safe houses, or small jobs when needed.
