What is a sarco used for? sarco battling strategies in ARK: Survival Ascended & Evolved.
I really believe Sarcos are one of the most underrated creatures in the game. Yeah, on land it's kind of pathetic, but it's high swim speed coupled with the ability to shoot while mounted make it EXCELLENT for taming aquatic creatures. I prefer using it over ichthyosaurus.
Shoot the target, swim away when it gets too close, rinse and repeat. Or lure targets to the coast and shoot them from the (relative) safety of the beach if you can.
Just be careful if you go exploring the Deep Ocean with them. Combat-wise, a high level Sarco can handle anglers, megalodons and even plesiosaurs (provided you have a good saddle), but you're better off running from everything else. Thankfully they have good stamina and can out-swim most everything that lives in the water.
This thing is probably the best possible animal you can have for water. The stamina regenerates instantly in the water and are super fast. They are lean mean fighting machines. It is actually really easy to tame as long as you are in a high spot and have tranq arrows and a crap ton of meat. I think that the only down side is that for some reason the food always goes down really fast, so always have a lot of meat in your sarco. I named mine Stanley.
dude, these are such underrated beginner tames! i tamed my first one when i was level 20 and it has been with me all the way to end game! once leveled up well these speedy tank like damagers are great for the swap, lakes and beaches. the only bad thing is if you do take early level you have to wait for its saddle at level 35.
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.
I have just started on Abberation and tame as many low level sarcos as I could. I have 10 now and they melt through everything in seconds. Spinos just disappear and they killed an alpha karkinos without any dying. I would absolutely recommend taming a few of these early game.
These guys are incredibly underated! You can easily tame one using bow and some tranq arrows or even the club since you can circle around them and they'll not be able to hit you plus they're good for early to mid game as a combat tame and the speed on this guy is unreal in water!
