What is a mosasaurus used for? mosasaurus battling strategies in ARK: Survival Ascended & Evolved.
Seems to be the fastest on mobile, outrunning even my icthy. To tame safely get an icthy, and stay on the ascension roof. Follow if it dives deeper to re aggro then get back up again, then shoot with toxicant arrows(only on mobile) or tranq spear bolts (not available on mobile it seems). Best tame, has a very high weight and speed and melee dmg, but has a bit of a pain in the ass turning radius. Easy to tame though, on mobile use a soothing balm and some prime meat taken from nearby basilosauruses or normal raw meat (raw meat is better at taming most stuff in the water than fish meat). Best thing to use for though is taming a tuso, as it can survive long and is powerful enough to even escort you and the tuso back to base. Best way to kill is with a high level basilo or another mosa.
With the platform saddle you can put turrets and all the stuff you really need for an base I tamed an high level one built and dome shaped base with turrets on top of it and used it for the underwater caves and melted quite an lot of Krakens and other nasty stuff ,since I also had my Frabicator I also could reload the turrets easy as well. Mind you make sure you use metal or higher since anything below would probably break after you get attacked by anything bigger then an megalodon.
