It cannot create Omnipotence, Ultipotence,Metapotence etc.

It may struggle to create Omnipotent abilities such as Almighty Magic and other abilities of that level. but this is up to debate and can be different for users.

Anything below these boundaries is free reign. anything you can think of to this point you can do.

It probably cannot create another MAC. That would be super redundant unless it was a totally different system of creating powers than the previous one.

it can create aspects of omnipotence but not like true omnipotence itself, it had the potential to, it can actually create ultipotence, and metapotence, and can also create omni powers of all kinds, but it can create true omnipotence its going to take a lot of work
