IMO, they can not cast sorcery, but: They expand the number of spells the priest can learn by adding their CHA and they may add their INT to determine how much manipulation can be done. This is most like the case for Malkioni.
The answer from the internet seems to be: "the specific outcome would depend on the terms negotiated between the parties involved and the prevailing customs and practices of the time."
Seems like it would depend if the party is ok with having Wolf Pirates upset at them.
Although I prefer Dodge over Defense, I do agree that Dodge has significant issues, especially in RQ3. Overall in my opinion warriors Dodge, soldiers use Defense..
