Additional Reliable Talent

Beginning of 3rd level you have a certain skill that you nearly perfected early in your life. Pick two skills that you are proficient in and 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 can swap the skills with another skill that you are proficient per long rest.

Fast Hands and Climbing Mobility

Starting at 3rd level, you can use the bonus action granted by your 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.

Additionally, you gain the ability to climb faster than normal; climbing no longer costs you extra movement. when you make a running jump, the distance you cover increases by a number of feet equal to your Dexterity modifier.

Audacity

You can give yourself a bonus to your initiative rolls equal to your Intelligence 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.

Last Minute Fall

At Level 4 you are so experienced with climbing that Fall Damage no longer applies to you. When  Falling you can use your reaction to gain the effects from the spell Feather Fall.

Use Magic Device

By 9th level, 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.

Thief’s Reflexes

When you reach 17th level, you have become adept at laying ambushes and quickly escaping danger. You can take two turns during the first round of any combat. You take your first turn at your normal initiative and your second turn at your initiative minus 10. You can't use this feature when you are surprised.
