Skills of the Trade

Starting at 3rd level, you excel at scaling structures. You gain a climbing speed equal to your walking speed, and this movement doesn't provoke opportunity attacks. You have advantage on any ability checks to climb, hang from, or grab onto a vertical surface. Additionally, you are a seasoned tradesman, gaining the following benefits: 
-You have proficiency with carpenter's tools and mason's tools. Your proficiency bonus is doubled for any ability check you make that uses either of those proficiencies. 
-You count as once size larger when determining carrying capacity and the weight you can push, drag, or lift. 

Controlled Falls

At 3rd level you learn to control your falls. When you fall at least 20 feet, you can adjust yourself in mid- air and shift up to 10ft in a horizontal direction without expending your movement.
In addition, you can use your reaction to redirect your force at a creature or object that occupies a space on the ground directly below you. The target takes full damage equal to the amount normally applied at the end of a fall. If the target is at least one size smaller then you, you also use it to soften your fall as a part of the same reaction. If the fall distance is no more then 20 feet, you take no fall damage. If the fall distance is more then 20 feet, you take half as much fall damage, and land on your feet. Once you use your reaction, you are shunted to the nearest space that you can occupy. 

Falling Strike

Starting at 9th level, you drop from above with deadly precision. If you fall at least 20 feet and make a melee weapon attack against the target of your *Controlled Falls* feature at the end of your fall, you have advantage on the attack roll. You can then move away from the target without provoking an attacking opportunity from it, as you tumble out of it's reach. 

Trained Resilience

At 13th level, you toughen against occupational hazards such as soot and chemical cleaners. You have advantage on saving throws against poison, and you have resistance to poison and acid damage. 

Incredible Heights

When you reach 17th level, you can leap extraordinary distances. Your jump distance is tripled, and you can use Dexterity instead of Strength for you jump distance. Additionally your Sneak Attack damage against the target of your *Falling Strike* feature increases by 1d6.
