>>5659187>How common are possessions by demons?Usually not all that common. Both the Named and Unnamed can possess mortals, they just need a way to get to the mortal world first. The most common reason for a possession is because some demon has beef with someone in the mortal world and wants to torment them. That being said, most stronger demons usually either have better things to do, or have cults and subordinates to do their dirty work for them. Speaking of cults...
>Can rituals and sacrifices in the mortal world affect demons in hell outside of summoning?Of course! Sacrifices by mortals in the True Name of a demon grant great power, as their society at its core is based on worship, fear, and strength over others. There are also other rituals to beg boons from demons such as knowledge, slivers of power, minor minions, etc. Many are always willing to bargain. For a steep, often unseen cost of course.
