Start with 11 points on Mobility: We maxed out Marathon Runner and Youthful lungs with the obligatory 1 point on Nimble Climber.
Then we maxed out Survival: Prioritize Looter's Instinct and Silent Scavanger for better looting, then level up the perks to get In-Round Crafting and add the necessary points to get Suffer in Silence and Good as new but don't max out Agile Croucher or Revitilizing Squat until the end. After this the perks we get choose are personal preference as they either benefit specific cases you'll find like being Over encumbered or needing to craft more items, we do have to get Security Breach for this build to reach it's full potential.
Finish by leveling Condinitioning and finishing Mobility: We are going to put the 22 points on Conditioning for better escapes and survival as well as more stealthy looting, as for Mobility, the reason i don't pick any more perks from this tree is due to them being very weak and needing either high investments to get their benefits.
