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
These bad boys/girls only spawn in the artifact of the cleaver cave on mobile. They’re relentless during the night time so only knockout during day time. Oviraptor eggs will be the most time consuming part of trying to tame a mega.
