SCP-2508 would be a small sphere (of undecided size) made of a unknown metallic material, strong enough to break a industrial strength compactor, if one is used on it. When the object would come in contact with some sort of material or chemical (I have yet to decide on the specifics) it would emit an unknown form of radiation in a radius of 20 square meters, knocking out anyone in that area. After around an hour they would wake up, with a strange urge to bring more of the material to SCP-2508, while not actually touching to two. An hour later they would experience random bouts of homicidal rage, 2 hours after that they would begin to attempt to bring people to SCP-2508. After this they would immediately bring SCP-2508 and the material together. 3 hours after that that they would begin a process similar to melting, and 30 minutes after they would be a puddle on the floor, which would quickly condense into a highly brittle form of the material that SCP-2058 is made of. Note that this is a VERY rough draft of the idea, and as such I would highly appreciate and suggestions or ideas!
This is a thing that has a weird effect, then makes you crazy, then does more weird stuff, then kills you. It honestly seems very scattershot and, well, not interesting at all. Even old articles about dangerous stuff generally kept their basic description simple enough.
I am probably one of the biggest advocates in these forums for weird and unexplained (not devaluing other writing tropes, just that occasionally an object's mere existence provides enough narrative to not need anything else), but this is (at the moment) literally a bunch of random effects strung one after the other as part of a ritual that does not seem to serve any real purpose. You need a central concept (even if you don't explicitly state it in the article) that ties everything together, one that hooks your reader.
The idea was the idea of the object attempting (but failing) to replicate, I will either scrap this or make that clearer
I get that's the supposed end result, but the steps taken in that seem to be there just to be spooky. Convoluted rituals can exist (see SCP-2845), but those have a set-up that makes in somewhat clear why those must happen.
If you're going for object-based horror, don't just start with a bunch of tropes and apply one after the other. Start with a relatively simple concept and then add other things only if they make narrative sense. Also note that recent successful horror articles (since the wiki is no longer just horror) are generally not as much about how dangerous something is but rather about what happens around it.
