An easier way is go on a itchy and find the nearest ammonite and hit it and them go slowly with the rage effect until you find one and yes i know a lot of sea creature will come so be carful when you do it (maybe you can find a squid like i did)
JUST TAME A SQUID GRAB THE MOSA,DISMOUNT THE SQUID.....and put the Squid on passive I will no let go of the mosa.AND THEN THE SQUID WILL BE DOING TORPOR AND ALSO YOU CAN HARPOON IT OUT AND TAAAAAAAAAAMMMMMMMMMMMMMME!!!!
A good way of looking for these things (mobile): sweep the border of the map and the ocean floor, using an ichthy to keep everything away. Once you find one, park your ichthy somewhere, then swim up to the depth limit of the mosa (you might have to test where it is though, be careful, mosas can swim up FAST). Being off the ichthy will catch its attention. Swimming up to the depth limit will cause it to Aggro off of you, so go back and forth with going to its depth limit, attracting it, and swimming back up to fill it with tranqs. The basic idea is attract, swim up, fill with tranqs, repeat. Hope this helps!
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!
Center tip: as they have added the mosa to the center I've found the easiest way to knock one out is find one close to the bubbles get its Agro and swim in the bubble the mosa will get stuck and it can't hit you. Also this gives you unlimited oxygen and sanctuary from being attacked by anything else. ðŸ¤˜ðŸ¼
very useful to hunt drops on, only issue is jellyfish dismount you and will kill it. in my opinion it's better to use a squid they have more health and the melee is just as good. until wildcard stops jellyfish hitting this thing it's a risk your loose it to a lagging render field.
