Having braved countless hostile environments, you've developed survival instincts and the ability to adapt to any situation. You gain the following benefits:

• Versatile Fighter: You have advantage on saving throws against being frightened. Additionally, whenever you take the Attack action, you can use your bonus action to make a grappling hook attack. The grappling hook functions as a ranged weapon with a range of 30/60 feet. On a hit, it deals 1d4 piercing damage and the target is grappled (escape DC equal to 8 + your Strength modifier + your proficiency bonus). You can ungrapple a target as a bonus action.
• Resourceful Survivor: You have an uncanny knack for making use of seemingly useless objects. You can use your downtime to scavenge for parts or materials. Given enough time, and access to basic tools, you can salvage parts worth 10 gold pieces within an hour. You can also attempt to find useful items or equipment within a natural environment or abandoned structures; the DM determines the availability and usefulness of such items.
