I play official and have tamed a couple of these there simple but hard to tame first u want to trap it then u might need a second player to stay close to it so it won’t go out of the trap when u get out of tender distance then u find the swarm fish and u can use the HLNA drone to scan the fish to see what lvl the swarm is depending on the lvl the less swarm fish u need so if u find a 150 swarm u will be able to tame any lvl megachelon off that single swarm but u must sit there and watch it when I did it the first time I wasn’t looking and it kept resetting the taming bar even tho there were not enemies nearby so u have to keep watching it while it tamed or u can tame it with the glitch and all u have to do is do the same thing except soon as u Afro the swarm fish on the turtle use HLNA to teleport away and watch ur tribe log for when u tame it it will tame eventually while ur at ur base doing whatever hope this helps 👍🏿
DON'T BOTHER DEFENDING THE TURTLE FOR 30 MINUTES!!!! Lure the swarm to it and then just leave render... If no one is near the turtle while the swarm tames it nothing will bother it and it'll tame out on it's own... EzPz
Ps: If ANYONE is in render it won't work, so wait until pop is real low to use said strat.
