Some people are saying "Trap Sarcos", but I have a quicker and easier technique (MOBILE). 1. Find a sarco. 2. Lead it to a dino that wont attack it. 3. Make sure NO dilos are around. 4. Go to the sarcos legs by its tail. 5. Make sure your bat is equipped. 6. Hit the sarco repeatedly. 7. If the sarco is knocked out, on whatever taming food you are using to tame it, click "All Stacks" if you have alot, so more level can be put into the sarco, and it will tame a bit quicker, and the taming effectiveness will be a bit high. No matter how much fish you put in after the first batch of taming food or fish, effectiveness will not go up, so thats why I included No7. In this tip. You will also want to go for high sarcos, even though they require a bunch of meat. In that occasion, always bring 15-30 Bio Toxin with you. You might need it. Also, bring cooked meat of whatever kind in case you are hungry. And 1 more thing. Its important! Always make sure your sarco is NOT INJURED, or health has been stripped away from some aggro dino. If that has happened, make sure you RUN away from it, so it can heal. If you bat it or hit it after it has had hp stripped away, you will kill it. UP this if it is helpful. I managed to tame 3 sarcos with this mechanism. But one died to a stupid manta. R.I.P Princess Sarcos.
