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.
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).
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.
