As I announced quite a while ago, we have now capped the maximum favor you can gain with a god by doing rituals at his/her shrine (example: Zhakrin scale, Asral sacrificial pit, etc.). If you want to raise your favor above the limit, you will have to attend sermons. If you fail to attend a sermon, you will lose favor in proportion to the amount you already have.

In addition to that, if you ask a shrine priest about “sermon”, he/she will tell you the time that the next sermon will take place.
