I haven’t created a new Cleric Domain for awhile, and felt the need for a little Evil.
The following Evil Domain is more for an NPC than a PC, but if you can get your DM to go for it more power to you. The spells would be handy in combat and other situations, but the powers are more for flavor and working in the background. Many of them require your DM to be complicit in your nefarious plots, which is cool, but sometimes can cause issues with your group.
Let me know if you have any comments. Back to the dungeon mapping for next time.
