Cults are the most difficult skills to master. Not only do you need to obtain the skills, you will also need to find the spells that are used by cultists. Furthermore the actions cultists need to perform are not very well accepted by society. Cultists need to contact demons for many of their raw materials and, in exchange will have to give demons goods in exchange. However, London depends on cultists since they are the only ones who can make certain goods including ammunition and wands.
There are two popular cults that sprung up after the demise of the old faiths and they are called the Cult of Succubus and the Cult of Inquisition. Both are mutually exclusive and you can be member of only one cult. Furthermore you must live your life accordingly so that your morality moves up for Inquisition and down for Succubus. The respective skill pages describe the requirements to learn each skill.
One of the benefits of cultists is, that they are able to cast spells. Another one is that cultists of level 4 who decide to use the Go To Hell death option can become demons in hell. Characters who don't have a level 4 cult can only become simple zombies with less power.
