Cattie Brie's 5e stats? (spoilers for The Companions novel)

[Sitara]

So The Companions was released in 2013. The events of the novel indicate Salvatore had some knowledge at least of 5e. The Weave is restored, and spellcasting is like pre 4e again.

Now in 3e terms Cattie Brie/Ruqiah would be a Mystic Theurge. But what about 5e? Since she called down lightning it can be assumed she is level 5 as a priest at least, with a domain giving her access to call lightning (nature domain in 5e terms?)

So are the rest of her levels in Wizard?

Or do you think she has access to some wizard or cleric subclass that is similar to Mystic Theurge?

I think multiclassing wizard and cleric simulates the 3e mystic theurge pretty well. Access to both classes' spells, no diminished casting ability but less powerful spells available.
