A tip for newish-players: My Sarco is still only a level twenty-something, by even by level 7, she was killing Titanoboas and kiting megalodons with ease. I can't recommend the Sarco enough as a swamp hunting mount-- and as I said before, ESPECIALLY for Titanoboas. You'll have leather coming in by the hundreds. Just be careful that you go at them head-on, and that you don't take on more than a few beasties at a time. Be especially wary of the Kapro. They'll knock you flat and leave you vulnerable to whatever horrors are crouching in the shadows. Have a pike on hand for those pesky bugs that your Sarco can't reach. And beware, dear reader, the frumious Baryonyx, with jaws that bite and claws that catch. They have a penchant of attacking from the side, making it quite a hastle to get back at them. (At least, from my experiences.) Want to take on other Sarcos with your Sarco? Have no fear. Just get your melee damage up a little bit, and you should be fine.
But as always, tread carefully.
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
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!
Do not kill something in the water near a tamed sarco on aggression target, it will glitch the sarco to spin around in circles and will eventually pick you up and possibly crash your game. It’s cool though.
