I wandered in a swamp with a long way from the exit when I encountered it, but what I came for to the swamp was tame something big since I had killed 2 therizinos and had lots of prime meat so in the end I used like 10 tranqs while frantically escaping another 2 boas, in the end the sarco fainted and along it me after killing the boas, I stressed fearing it would wake up before me and when I did all it took was 1 prime meat :3 surprisingly easy tame! I called em SharpTooth cuz it almost tore me in half.
