Good mount to take into rivers and even the ocean. Good for hunting fish and I've even seen it beat a megladon. But never use it to fight a Rex because if things go south it is a very slow land mount. Short and sweet it is a hunting mount
I see all these comments on how to tame it lol. Easy. Shoot it in the face while walking backwards job done. None of this tame pen rubbish or hugging its legs. If you get one in the swamp your gonna want to lure it out of the swamp though
TLC patch coming March 2018 adding "Deathroll" grab attack on small creatures and a grab attack (possibly thrash) on larger ones, gaining a 180 degree attack and a small lunge to its attack (maybe for deathroll purpose), will no longer aggo pirahnas and in the wild will sit with mouth gaped open awaiting prey. Like so people can see!
In my experience I have found a couple of ways of taking these big boys down easily. The first one is to utilise it's turning circle as it cannot turn fast at all, so hug it's back legs, turn with it and whack it with some sort of melee weapon at the same time, a sword or pike works best for this. The second technique is to just walk backwards and shoot it with something, preferably something damaging, so I wouldn't suggest using a slingshot here. But doing this back step technique will allow you to just be too far away from the Sarco's bite, however, be careful of what can come sneaking up behind you. And by all means do not try and out swim this thing, it will win, every time.
It's better to tame one you find at a beach/river than one in the swamp. The swamp has a lot of dangers that can make taming in there a nightmare (namely titanboa and other sarco, but leeches are not fun either)
You can find them near pretty much any body of water. Sometimes they are hard to see if they are in the water. They will follow you out of the water, since they are much slower on land try to lead them away from the water.
A swift and tough mount, even on land. Even faster in the water.
Attack speed is slow, and the attack range is a small, wide cone, so enemies that are next to its neck tend to not get hit, but keep the enemy a bit further forward and the sarco will be capable of killing it quickly.
Will get stuck on trees easily, can't fit through standard dinosaur gates, and will take wide turns when following.
Sarcos are very slow on land so use a crossbow or better to tranq them so tame on land in and around the swamps or in rivers and ponds. DONT ESCAPE INTO THE WATER THEY HAVE A STRONG BITE AND ARE VERY FAST UNDERWATER!
When riding on a boat keep an eye out for these guys because unlike most other water dwelling predators, sarcos can still see you and attack you on the raft. If it gets to you it will be hard to shake off the raft, it'll make the raft move buggily, and if you don't act quick it will ruin anything you're carrying on the boat, and can of course kill you, most likely leaving you're raft stranded. If you have a partner have them stab it to death, they are weaker than they look. If you're alone, try to get as close to shore as you can and fight it off there.
I think Sarcos are amazing mounts. When in water, they are decently fast and don't have an oxygen stat. Also they don't run out of stamina because it doesn't go down at all. They are also pretty good land mounts. Although they are very slow, they are pretty powerful. I wouldn't suggest fighting anything harder than a pleseosaur and on land nothing harder than a Rex. All in all, I think Sarcos are amazing mounts!
