Do you want an underwater giga?(say yes or else)well, ive got you covered! So lets get right to taming. Diff 6.5/10(scuba basically required)

Youre gonna need:

-any fast water mount like an ichy or a sarco

-a LOTTTTTT of tranqs

-highly recommend a good crossbow

-at least 3 behemoth gateway and 2 gates or if youre using underwater caves 1 gateway and 1 gate

-narcotics to keep the mosa asleep, i use biotoxin

1. Set up trap. Place 3 gates like this: | | |. Use even ground if possible and just keep one gate in your hotbar. If in a underwater cave place gate at entrance.

2. Trapping. Aggrothe mosa and lead it in, stay in the trap until its in or it will go sideways. Just put the gate at the back gateway once its in.

3. Knockout. Knock the mosa out cold. Kill or lead away all creatures that might interfere with your tame. Use harpoon launchers crossbows and bows(not recommended but works)to knock it out.

4. Feeding. Give it your narcotic of choice to keep it asleep while it eats. Exceptional kibble or above can be used or quetz kibble if youre on mobile. If you dont have that, just use prime meat or mutton.

5. And there you have it! A sea beast. They do insane damage and are extremely fast. They have a tek AND platform saddle that you can build on. As long as your mosa was strong enough you are invincible in the ocean. Anyway thats all folks, ill make a argy tip next.

Tamed my first one with raw prime meat from killing plesiosaur took about 17 and using their prime meat to tame a level 15 with a 98% taming effectnesss about 30 minutes using a harpoon and tranq spears to knock it out i made 29 took about 23 although I think i misses 5 or 6 shots so take that with a grain of salt but use a deinosuchus they take 50% less damage to the head so face it head on make sure it has a high health pool 12k or more which is extremely easy to get to one of mine is level 180 close to 13k health and 400% damage thay tank the ocean creatures as long as you don't get surrounded by 30 megs like I did sadly the Mosasaurus did not survive before I could crypo it i had 30 megs and two alpha 110 megs run up on me so sucks for me hope you guys have better luck then me

Hi, today i tamed my firt Mossasaurus and heres how you can to. I used the anmomite rage efekt to lure the mosasaurus to a island, and then just shot it with a crossbow you can shot it with darts but I forgot mine, anyway you can use prime meat or pirme fish meat. i used bio toxin to keep it a sleep it works really well. I tamed mine and im only level 60, anyway hope

this will hlep you tame your first mosasaurus.

Why are there’s in mobile yet nobody has one...I think finding one is hard but if you find one remember where get a basilosaur and go back to it with harpoon tranqs and ko game it and give it meat...THIS DOES NOT WORK ON ALPHAS,YOU AND YOUR BASILOSAUR WILL BE DEAD(or just swim away and look like a wimp)hope this helps!

If you have a squid and a tribemate then it’s a piece of cake. First you grab it with a squid and swim up till the other mosas can’t get to you then you have your friend tranq it out while you’re holding it. If you’re lucky you can get it close to land and your friend can use tranq darts

just tried taming one with tuso cause I've seen just about everyone say that you can grab it with squid and dismount to shoot it and it didn't work, I tried same thing on multiple other creatures and my mosa I tamed b4 squid and squibwerb kept letting go of them everytime I dismount. it's better to bring it up to a shallow area where it can't go back down to deep water like the coast of main island on lost island at the south or desert coast, they will swim forward a trying to go down until they hit a wall can't move anymore and you can safely dismount and ko them without chasing them throughout the entire ocean(what I did for first mosa) or them attacking you. do bring more arrows/darts than app says my lvl 135 did not go down with 14 arrows

In Genesis, there is a section underneath the Ocean E spawn where there is a glitch pass the big tek door that allows u to swim inside. I baited a mosa inside there and placed one behemoth stone gate down on him and tranqed from the top of where my base is on land shooting down on him. Yhere is currently another one there as we soeak but it's 4am and I make 9 lol

On ASA, just tamed one, lvl 150, on a boosted server, maybe 3x. I took 4 behemoths gates, I placed them like a cage under a cliff on the bottom of the sea, so the top part is covered by the cliff. I lured the Mossa inside the cage with my Basi and trapped it, then via a small gap I shot it with the ascended crossbow (400% damage) 50 - 60 Tranq arrows, feed it with at least 7 Extraordinary Kibble and 200 Narcotics to be sure it will not wake up before.

Pro:

It's very fast in the water, I want to race it against the dolphin, it might be faster.

Good at collecting meat, gel, biotoxin, hide etc.

Cons:

Can't reach too close to the shore because it's getting beached.

The turning radius is horrible, if something is attacking you from behind it's very difficult to turn around and do some damage back.

It's loosing health faster than Basi

(Mobile) You set sail to die, I mean tame a mosa. First you find one. Then make a cage without angering your surrounding wildlife. You die because you are too low level and you try again later. You finish the trap (4 behemoth gates closed on the ends.) Open one end swim through with you god chasing you. If it is trapped you can swim out through the side and close the gates. And then you shoot till its out. Keep it asleep with narcs or bio toxin while taming with kibble or prime. After a grueling amount of time fighting everything off. If you succeed you will have your new giga of the sea.
