You can either knock them out during the day, or you can knock them out the moment they wake up at night. It is far safer to knock them out during the day because they will be sluggish but you will have less time to starve them unlike if you tranq them after night. Note that more than likely you will have it wake up because no matter what when night hits they will automatically wake up which is why you must starve them before you tame them. This makes them a challenge to tame for some people. However with some patients and practice you will get the hang of it.
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
