Mantas are very quick ocean transport mounts, which also double as a powerful PVP asset. The manta's attack ignore the armour stat, which makes a high melee damage manta incredibly powerful to players and small tames. It's quick speed also allows it to move very fast. It can jump out of the water, but on contact with land, it will begin dying very fast. Very good for travel on the center map, as it can jump over the many islands if it gets a good run up
Incredibly fast mount. If it touches land it will die in less than 1 second. Very very low hp. Tame it naked. It ignores armor so save your mats. Build a trap, pin it down with as many pillars as you can. Place a stone hatch on top of him. Expect to die. A lot. Like, a whole, whole lot.
Fast, armed with an armor piercing barb, capable of jumping and easy to breed, Mantas are the best scout mounts and bodyguards a player may have. As a bonus it is also possible to stand atop of them.
Their only drawback is not allowing the use of weapons by their riders, a trait existent on the similar speed oriented Ichthyosaurus.
Their damage gain per point spent after tamed is also about half the usual (and similar to the Giganotosaurus). However, given their high base damage, ability to (greatly) ignore armor, small turn radius, and poor health scaling, leveling Melee Damage still proves to be the best option for combat Mantas.
Once tamed basically fancy looking combat icthys but can't let you hold weapons on them but they can leap out of water and they work a kind of as a "fear tame" you need to go deep down and risk the dangers to get the gel mantas want to tame so that means if you have loads of mantas enemy players might think twice about attacking you fearing you might have powerful weapons either from simply being high enough level to get the gel or from deep sea loot crates
