Is there an existing Cause Unrest option? If so, awesome! (You can see how often I've used offensive Priest mechanics.)
Under "Influence followers" you have the following options:
scareBy spreading tales of doom and destruction, you will cause morale in the region to fall.
calmThe opposite of scaring people, you can calm them by telling them about the mercy and strength of their gods. This will slightly improve morale and very slightly reduce independence.
cause unrestGathering enough of the believers, you can try to stir them up into a frenzy and cause civil unrest in the region. This will raise independence and lower production. There is a small risk that the local militia will arrest you.
badmouth realmYou can use religion as a political tool. Speaking about the sins of a realm, or that the gods despise it and its government will cause the locals to reduce loyalty or sympathy towards that realm.
Note that clashes with politics cause casualties on both sides. This option will cause you to lose more followers than the simple ones.
laud realmYou can use religion as a political tool. Speaking about the virtues of a realm, or how the gods approve of them will cause the locals to improve their opinion of them, raising loyalty or sympathy.
Note that clashes with politics cause casualties on both sides. This option will cause you to lose more followers than the simple ones.
All these options are reported to the people present in the region, and their success depends on the number of followers are your oratory skill. They also all lead you to lose followers.
Fair point. I was thinking of offensive uses of religion in general, and I think you are right that it would be better for a region lord to repurpose temples. Unless...What if we just make it a requirement that you can only repurpose a structure to the faith of the current lord? That would actually make the most sense, I think.
That would make it realistic too. I'm not sure if you should need the Lord to approve of the conversion, or if his appointment is enough to assume he wants the temple converted.... Tolerating a temple of another religion can be politically important, but allowing priests to forcefully convert the temple may lead to interesting results.
Edit: "Realistic, also" and not "realistic too much"
