They are, in fact, a rather easy early game tame for ragorok map. In the Viking bay, there is a chance for one to spawn under a large skeleton, so you can get it out rather then a cave. Just watch out for rexes.....
I went to the central cave and knocked out a level 300 female megalo, but it went into the water before unconsious and then died there due to oxygen. Now I have it's implant of level 300. Should I revive it with the cost of 31 Amber's? Is it any worth to invest that much of ambers for it? If yes then up and if no then down.
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
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
