I suck at challenges but was lucky enough to be on a tribe that won most of them anyways. I merged twice and then early after the second merge I ate without fire. My stats were super low but I managed to survive until the final day. My stats were at 0 but i thought I would be okay since we were merging at day change. Unfortunately thats not how it works and i died :(
Overall, though, I'm proud of myself for making 2 merges in my first survivor game!
