Ever since GEN IV, night time has been regarded from 8:00PM onwards til morning. So in order for your Amaura to evolve, your DS time/game time must be set to or you can wait at in between 8:00PM - 5:00AM. 2 years ago 0 0. Hyper_G answered: You're missing one important step. The Amaura has to have a high friendship as well, or else it won't evolve. Make sure its Happiness value is high by playing with it in Pokemon Amie, letting it hold the Soothe Bell, etc. then evolve it after 8:00pm. 2 years ago 0 0.
