Sadly, I had no torch batteries left, so I was stubbling around in the dark looking for the Rat King.
Lucky, I had robust genetics, and the Ratting gave me Nightvision after a short while. Then I found the rat king and beat him to death with the nice sharp combat knife I found in his cave.
So yeah. Total loot for all that? One shiny combat knife, a suit of light power armour (!) and about 6 mutations. Sadly, I ran into a Hulk shortly after leaving the cave, and got splattered across several trees, but hey. You win some, you lose some.
