Heh… if you want a bit of fun, you can have some of the sneakier gods transfer a fraction of their power (whatever they can manage) to their most devoted follower(s). You've got plenty of control over what that entails, how much the recipient knows in advance, and how much can be communicated.

Any death god might even have a gambit in place to get themselves reincarnated. That leaves a cult of powerless but resource-rich clerics out to cash in on the major rewards a job well-done would entail.
