I just wanted to re-iterate that mixed worship (e.g. we worship both
gods and spirits) is distinct from misapplied and has no penalties.
People who do not concentrate their magic can worship many different
entities, in their correct manner (i.e. not misapplied). Only
concentration on one magic system prevents this.
So a Pol Joni who does not concentrate may worship both the Storm
Tribe and Praxian Tradition without penalty.
