The cave under Viking Bay on Ragnarok you can use wyverns. As soon as night hits, stand on wyvern and shoot the Megalosaurus hop off and run underneath your wyvern. They don't take many darts and won't be able to attack you underneath your wyvern. Easy work!
People say that is easy taming on day rather than night, but thats not truth because they always wake up, no matter how much torpor they have at 20:30 in game, that will cause you to lose all your taming process, I always tame these guys by starving them 2 times and then the 3rd knockout I put the food on its inventory, thanks for reading
Tame the mega during the day! It is extremly slower during the day due to wanting a rest. It is a very strong dino, it has been tested to be even stronger than the allo! Be careful if you tame it at night ;) caw
