Pro tip: Don't use explosive weaponry and really bad rexes with no saddles like the devs did. Fab Snipers for taming it with little/no collateral damage, actually decent rexes + imprint + saddles to kill it (Probably not for this flying one tho lmao).
If on a non official, use a lightning wyvern at around 250 with mainly attack damage and stamina on it and then only use lightning breath unless ur a dare devil then u can bite but anyway I rekt the dude in less then 3 minutes. Simple
You have to hit the corrupted part of it it will bulge out of it and then if you destroy all them it will be tamed the taming effectiveness depends how much damage you do to the creature more damage lower taming effectiveness lower damage higher taming affectedness that is how you tame the giant desert manta.
Use a Quetzal and a pretty good one. Block off your head with foundations so the swarm can’t get you off. Then use the lightning on the corrupted spots and just keep doing that it’ll tame itself. Another tip you can fly under it and it will work too.
To kill it without flyers, Get a strong velonasaur and bring it up to the titan flying by using the geysers. Once on top shred it with the right click attack, when you are about to fall on the titan or it knocks you off, just dismount before you hit the ground. Rince and repeat. Kill the flock before it dismounts you.
