How to tame a sarco:

1. Build a stone trap. A 2 by 2 foundation and doorframes for the walls. Make it two doorframes high. And use ramps so you can walk into the trap to lead the sarco in there.

2. After the sarco is stuck in the trap, shoot it with a tranquilizing ammo like tranq arrows or certain darts.

3. After it's knocked out, feed it meat or preferred kibbles.

Hope this helps!
