A reinforced DigiEgg is a hatchable egg who don't break or get failed data input. This kind of egg has a certain level (from 3 to 5), wich indicates the number of data you can and must give to it before hatching it. It is impossible to hatch it to a superior level.* It also has a specified stage indicated in its name. This means the Digimon you'll get by hatching this egg has already unlocked stages up to the writed one.
- For that, you'll need special eggs with no level in the name and "100% Phase 3" in the description.
