The objects and desires of the supernatural are a mystery. It might want to be summoned to gain access to our world or some aspect of it or it may resent being summoned.
Well, then no.
Just don't make the "Say it ain't so, Joe" reference. He's probably heard that a billion times by now.
These random and oddly specific threads of yours lead me to believe you're living some sort of secret life you're trying to validate by getting outsider opinions before coming out proudly as some cannibal wizard that trades in body parts and drinks milk from cows that can talk before summoning supernatural beings for “reasons.” You do you, my friend; I don't judge, but I'll stay well away...
Hey, those cannibal threads were not me. Those were Masonicon.
Sure, but it's a personal sacrifice. What would you sacrifice?
What are you gonna do? Google it?
Quite probably, yes. Rocks with weird runes in some kind of pattern arranged on the ground. Google Image search runes until you find ones that match. Where are they from, what entities are summoned in the folklore of the dominant culture of that area? No runes, just strange ingredients in jars? Take a picture, reverse image search. Then Google for folklore involving those ingredients. Given Google and a free hour or two, I could probably get a pretty good idea what the ritual was meant to summon. Hell, crowdsource some help. Drop a picture on r/whatisthisthing. Get a reply from someone saying, "hey, that looks like a spancel."
As if true magical information would be easily and publicly available on the internet. You would probably find nothing but myths and fake info.
Yeah, myths and fake info. If we're taking the question at face value... we are basically already saying hypothetically we exist in a world where myths and folklore can potentially be real. Plus, cultural basis would still most likely line up. You aren't going to see Celtic runes on accoutrement scattered around an altar to summon a Zoroastrian demon. Plus, my mention of a spancel... earlier. Just the addition of such an ingredient in the summoning ritual is a pretty good indicator that you aren't summoning something "good." Basically what I'm saying is you can discern quite a lot about what you would potentially be summoning, by examining the summoning ritual itself. Even something nonsensical and stupid, like summoning the invisible swordsman in The Three Amigos. The instructions; find a singing bush, shout gibberish, and fire a handgun. They should have realized they were summoning something stupid enough to get shot dead the second it apparated. And if a summoning ritual is vague and incorporates several different languages and cultural references... then it is being intentionally misleading. Then I'm definitely not summoning whatever it is, if it is trying to trick someone into summoning it.
