You can take a bonus action on each of your turns in combat to take the Dash, Disengage, or Hide action.

You can use the bonus action granted by Cunning Action to make a Dexterity (Sleight of Hand) check, use your thieves' tools to disarm a trap or open a lock, or take the Use an Object action.

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.

Your proficiency bonus is doubled for Deception, Insight, Investigation, and Sleight of Hand.

Once per turn, you can deal an extra 7d6 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 have learned the secret language of thieves.

Climbing no longer costs you extra movement. When you make a running jump, the distance you cover increases by 4 feet.

When you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed and only half damage if you fail.

You have advantage on a Dexterity (Stealth) check if you move no more than half your speed on the same turn.

Whenever you make an ability check that lets you add your proficiency bonus, you can treat a d20 roll of 9 or lower as a 10.

You have learned enough about the workings of magic that you can improvise the use of items even when they are not intended for you. You ignore all class, race, and level requirements on the use of magic items.

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 as long as you have seen an example of the kind of document or handwriting you are trying to copy.
