Okay so I was walking one day with five meat in my inventory. The “dangerous area” sign showed up and I saw him. A sarco was standing right there. I had no choice but to fight it. Surprisingly it was easy. Only half of my health was taken. I was only level twenty so I recommended this for a beginner tame.
Get a bow with trans arrows (1-5) for low level, go on a rock if you are low level and shoot it with tranqs. However wait for it to finish attacking animals and other Dino’s or it may be killed by them when unconscious.
