This post is a part of the #RPGaDAY series for 2024. For more information, see this post at AUTOCRATIK.
The Day 3 prompt is "Most often played RPG," and if that means, like, over my lifetime, I honestly don't know for sure. My initial thought what that it was likely some edition of D&D (probably 2nd?), but after some consideration, it may actually be Cyberpunk 2020. If it's just for the year (or, like...currently), then it's gotta be Mountain Home (see previous post for more info).
Today's alternate theme is "Demonology," and I rolled a 4 for "Invent an item."
Sulroth's Communion is an artifact in two parts: a round-bottomed hammered brass basin and a simple oaken four-legged stand to place it in. Once the Communion is assembled, the user adds some quantity of flammable oil to the basin ("a mouthful is enough," confusingly states one grimoire). They then add some piece of themselves (hair is common) and some demonic element. They then ignite the oil, and in the resulting smoke, a demonic visage appears. The user may ask the demon one question which the demon is compelled to answer truthfully. The demon then asks the user one question which they are similarly compelled to answer truthfully. If the demonic element is some item related to a demonic sphere of influence, some random demon from that domain is contacted. If the item is of personal interest or connection to a particular demon, that demon can be specifically called. If the item is a physical remnant of a demon's body and the user's item caused the user harm when obtained, that specific demon is called and the number of questions allowed to each party increases to three. In any of those cases, once the questioning is complete, make a percentile roll. If the result is 02–99, the smoke dissipates and the ritual ends. On a result of 01, the demon may step through the smoke into the user's world. On a result of 00, the demon my bodily pull the user through the smoke into their own realm.
