Finished the Jabal Sag quest to become a desciple. Loved it. All religions should be reworked to have the same mechanics. Ie. the character must prove him/herself to the diety before being able to worship the god. All other religions pale in comparison to Jagal sag since it only requires some small talk to become a worshiper. That process is kind of boring and zero immersion.
Also, it would be neat to have more quest linked to gods. Maybe being able to craft a specific key that is needed to enter a dungeon. And as with Jabal Sag, resources needed for powerful religious artifacts only found/easily found in that dungeon.
