What is a sarco used for? sarco battling strategies in ARK: Survival Ascended & Evolved.
They have a really slow bite animation so what you should do is chain attacks with them by spamming the other skills. You need to spam leaps, turn your cam around towards the dino and basic attack before continuing the cycle. Many called it trash because it attacks slow but in reality, it has to spam different attacks in order to be viable in battles. Really fast underwater aswell.
The dododex speed says that the base speed of a tamed sarco is 1000, tho it got changed at the TLC. It can sprint underwater and it does make a difference. I think it's actual speed is close to 1500. Piranha's are scared of the sarco so they will never come near it, which is nice.
(mobile) Sarcos do not do well as a battle mount in deep waters. Not just because of their narrow attack range, low dps and slow vertical swimming speed. They consume food like crazy. Ever saw tips telling you this creature or that uses extreme amounts of food? Like Giga or Daedon? Well, Sarco is one of them. Its food stat drains faster than it can automatically consume, which is fine if you're going for relatively short trips like pearl diving or angler hunting, but it is a problem if you're doing something time-consuming like leading a Leeds halfway around the map back to your base. Even on high levels (442 after tame for instance) your sarco will slowly starve even when there's still a stack of meat in its inventory. An Icthy works better as a travel mount while most other underwater creatures are better for combat. If you're looking for an underwater specialist, only choose the sarco if you don't have access to other creatures yet. (Or use a bary)
(Mobile) Early-Midgame tame, quickly becomes useless after you acquire a good x-bow and tranq arrows. Mediocre health, somewhat good damage but extremely low attack rate and dps, low vertical diving speed, large turning radius and weird attack range...only saving grace is that it's unmatched in rivers, and compared to other midgame tames, very easy to kite/trap and knockout. However, the sarco's got two glitches in its favor. Spyglass and invisiglitch. Thanks to its long attack animation and high damage, spyglass can increase its dps immensely. And sarcos can be found and tamed in the Clever cave, it shares the other cave creatures's invisible glitch. Combine the two and you have an untargetable killing machine. Still not as powerful as the lategame predators and quite useless on multiplayer but still impressive.
