Difference between major and minor deities besides power level?

[ClingClong]

Is it that major deities are immortal and minor deities can die?

As in, major deities are more like embodiments of inviolable laws of reality where as minor deities embody mutable principles.

[Drahliana Moonrunner]

Nope. Only difference is place in the pecking order. And how many domains they grant.
