Take a tribemate and a strong water tame (I favor the Basilo) to distract and dispatch the megs quickly and not ruin taming effectiveness.

1.get colored loot(ramshackle apprentice etc)(you can get colored loot in these ways)(drop killed animal inventory’s)2.make rat fish treats. Rat fish treat ingredients. Tusoteuthis tentacles, ammanite bile, and giant bee honey.3. Find helicoprion. Helicoprions share spawn points with megs. 4.Taming helicoprion. To tame you have drop your colored loot by the helicoprion which allows you to ride it. Then you have to press certain buttons to stay on. Wait till its tired and you can feed it the rat fish treats.enjoy.

Who ever said it spawns in lvl 1 megs that is not true it spawns in random lvl megs just saying

After creating it’s preferred food in cooking pot (10 ammonite bile, 4 tuso tentacles, and 6 bee honey) put in last slot in inventory to feed passively.

Bring a few premade ascendent items (higher the quality, shorter the ride) toss out one item near it, it’ll then go to eat. When it eats item go up and mount it to start rodeo, it’ll then ask you to press a button (typically a direction on d-pad for controller players). Once it is tired, option to feed will pop up. Feed it, it’ll knock you off. Avoid for a little bit, then throw out another item to start again. Continue till tamed. Took 3 preferred food to tame lvl 60 on x2
