[@Kho] On top of Capy's valid concern, that would also require tagging creations with the level of the god at the time. That kind of extra record keeping would probably be confusing and difficult.

I've always assumed that the higher level gods can do more powerful things in a fuzzy and ill-defined way. However, I don't see a big advantage in adding a mechanical deal to it. The only time I would prefer to see raw levels being taken into account is in a tie-breaker between clashing actions by equally invested gods.
