Underwater Taming Setup
Taming a Mosa is probably the most logistically intense thing you'll do in ARK's ocean and honestly you need to prepare like you're going on an expedition and not just a casual tame, first thing is full SCUBA gear is mandatory because you'll be underwater for 2 plus hours and that's not an exaggeration, bring extra tanks because running out of air mid tame is basically a death sentence and I've drowned doing exactly that and it sucks losing all your gear at the bottom of the ocean where you can't get it back. Use a Basilosaurus or Tusoteuthis as your taming mount and the Basilo is honestly the better choice because it's immune to jellyfish stun which is critical for deep sea safety and nothing is worse than getting stung off your mount while a Mosa is charging at you, for the trap design you need 4 to 6 behemoth underwater gateways in a U shape and you lure the Mosa in then close the back gate behind it, if you're on a budget you can use natural terrain like underwater caves but that's riskier and I've had them swim out of caves before so gateways are worth the investment. For the actual tranquilizing you want tranq darts from a crossbow or a harpoon launcher with tranq spears and you're looking at about 120 darts to the head for a Lv150 which is a lot so bring extra, torpor management requires 800 plus narcotics because the Mosa torpor drains moderately fast and you need to check every 10 minutes or you'll lose your progress, the biggest danger is the Mosa's massive AoE bite and never ever get between it and the trap walls because it will hit you through gates if you're too close and that's a one-shot for most players even with decent armor, I learned this the painful way obviously.
Platform Saddle
The platform saddle unlocks at level 93 as a separate engram from the base saddle and it's honestly what makes the Mosa go from great to god tier because you get 50 structures on the platform and that opens up so many possibilities, you can build a full mobile underwater base with a bed and storage and a forge and a fabricator and basically never need to return to your land base which is kind of amazing if you think about it, place turrets for jellyfish and piranha defense because those little things are annoying and will slowly chip away at your stuff if you don't have defenses and honestly nothing ruins your day like coming back to find jellyfish have killed your tames, the farming base setup is where this really shines because you just build with storage boxes and farm oil and silica pearls and biotoxin in bulk without ever surfacing for air and the efficiency is crazy compared to making trips back and forth on a smaller mount, and honestly the coolest use is as a mobile underwater taming base where you tranq other ocean creatures from the safety of your Mosa platform because you're high up and most ocean creatures can't reach you up there, I tamed my first Alpha Tuso from a Mosa platform and it made what should have been a terrifying experience into basically a calm afternoon of fishing and that's when I knew the Mosa was the real deal.
Combat & Uses
The Mosa is basically the delete button for anything in the ocean and with 120 base damage it out-DPSes literally everything underwater and soloing Alpha Mosas and Alpha Tusoteuthis with a high level Mosa is totally doable and honestly kind of fun because you feel like the actual boss of the ocean, for deep sea loot crate farming the Mosa is by far the best mount because the enormous weight capacity lets you carry multiple crate hauls without having to surface and you can just cruise from crate spawn to crate spawn clearing everything in your path and you'll come back with more loot than you know what to do with, boss fights are where the Mosa really proves its worth because it's essential for Moeder and other underwater boss encounters and most tribes breed a squad of 10 plus for boss arenas and that's not overkill that's just what it takes. But the Mosa does have some real limitations like it cannot go on land at all and it's completely useless in shallow rivers where it gets beached and looks pathetic flopping around, the slow turn radius is also a big weakness because a Tusoteuthis in PvP can grab and hold you from behind and you can't turn fast enough to bite back which is incredibly frustrating, also the Mosa is so big that it gets stuck on terrain in caves and tight spaces and you'll spend half your time trying to wiggle it free which is honestly the most annoying thing about using one, still for deep ocean content there's nothing better and I'll die on that hill.
