Scrappy Survivor
Source
Ports of Call pg. 113
After extensive physical conditioning and practice in the field, you can force your body to keep going even when you have nothing left. When you’re suffering from thirst, you need to attempt checks to avoid nonlethal damage only every 4 hours instead of every hour. When you’re suffering from starvation, you need to attempt checks to avoid nonlethal damage only every other day instead of every day. You can also hold your breath for a number of rounds equal to three times your Constitution score instead of two times your Constitution score.
In addition, you gain a climb speed equal to half your land speed. If you already have a climb speed, it instead increases by 10 feet.
