Utility Tips

What is a sarco used for? sarco utility tips and strategies in ARK: Survival Ascended & Evolved.
These creatures can be tamed with tranq arrows fairly easily, although it may hard to determine the level so I recommend getting extra tranq arrows. After taming the sarco is VERY USEFUL given the time you can tame them if you are experienced enough, they have good dps, go extra fast in water not to mention they don't have to resurface for air. Great for traveling long distances with good defensive options. The one condition is that in the water there are cniderias or jellyfish if you will. If they make contact with you or your dino they will stun them and deal damage overtime. I highly recommend getting a crossbow to be able to attack from a distance because melee won't work, killing them in advance is good because they can move towards you slowly. If you can work with those complications then this will be a beast of a tame.
As I was body guarding my mate who was building a trap for a baryonx in a fairly dangerous area with my trusty sarco named Lamin I decided it was a good idea to make some bolas cuz we had just got jumped by a pack of raptors and we used all of our bolas so as I’m collecting the last of the fiber I get jumped by 1 troodon who was able to knock me out but lamin jumped into action and saved the day my takeaway is to always keep a pet sarco near you at all times.
Definitely one of the best underrated games in the game they are great for diving for pearls but can be stored on land they don't need oxygen, they can go into caves and enter the underwater bubble and you can easily tame it by aggro-ing it out of swamp, the kibble needed is also really easy to get and I got my 130 kibble tamed by collecting eggs on the beach
early game : 1) Fast underwater mount 2) maybe is good as defender of base against aggressive dilos. But i dont know if its worth the risk
Mid game: Has nothing to offer except eggs. Weak rideable experience with attacks that are more targeted to ONE someone so it cant fight more than 1 at time 2) health is ok, but with more than 1 at time this doesn't matter, you die (or have to run) anyway
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.
