You’ve survived the wreckage of forgotten ships and battlefields, learning to spot value in debris and make do with whatever you can salvage.
Benefits:

• Ability Boost. Increase your Intelligence or Wisdom by 1, to a maximum of 20.
• Scavenger’s Eye. You gain proficiency in Investigation. If you already have proficiency, you instead gain expertise (double your proficiency bonus) when searching wrecks, ruins, or derelicts for useful items.
• Jury‑Rigging. You can use Tinker’s Tools to temporarily repair or repurpose broken equipment, weapons, or ship systems. A jury‑rigged item functions for 1 hour before failing again. You can use this feature a number of times equal to your proficiency bonus, regaining all uses after a long rest.
• Scrap Sense. You have advantage on Wisdom (Survival) checks made to locate salvageable materials, hidden caches, or safe passage through hazardous wreckage.
