Summoning A Technology Based Demon

There are two kinds of summoning, when you really get down to it. There's the summoning where the summoned wants to be summoned, and there is the summoning where the summoned is compelled to be ...

Keeping the horde of nanomachines at bay?

The nanites use IPv6 for communication. Source of the image above: https://xkcd.com/865/ They are limited therefore to 2128 bots operating at the same time. Any extra nanobots are unable to ...

The best realistic spell to brick firearms

With most firearms, the simplest, quickest way to "brick" the piece (without killing or maiming anyone, including the users) is to weld moving parts together so they become non-moving parts. The ...

Could somebody get temporarily stuck/“glued” to a wall by way of energy or some other force?

Use tentacles. Lots of tentacles. You never go wrong with tentacles and there is never too much of them. A prisoner dangling from tentacles slithering over their bodies has no leverage to free ...

Justifying why a nanoassembler can only produce inorganic things

Simple Economics In theory, a nanofactory can produce (complex) organic materials, but it is plausible that it is terrible at wet chemistry. I assume that is what you want, as even methane or plastics ...

What is the minimum required technology to reanimate someone who has been cryogenically frozen?

Well, we can't do it now so the only answer we have is 'more than we have now'. Alright, this isn't strictly true, insofar as we can cryogenically freeze embryos and the like, and we can then thaw ...

How could I make something "immune" to nanotechnological disassembly?

Your ruleset has put you in a corner. You state that they can disassemble "ANY organic/nonorganic compound into their core components." The typical definition of "nonorganic" is "any compound which ...

Justifying why a nanoassembler can only produce inorganic things

Chemical reactions and nuclear reactions — two ways of turning things into other things — are easy. Both were done with 19th-century and mid-20th-century technology, respectively. Folding proteins ...

Could somebody get temporarily stuck/“glued” to a wall by way of energy or some other force?

Magnets Just make the shackles out of iron or some other metal, then place magnets inside / on the walls. Turn them on and off and there you have your "magically pinned to the wall" effect.

Could somebody get temporarily stuck/“glued” to a wall by way of energy or some other force?

G-Force The "room" is actually moving. It can be made to move very fast and will thus exert very strong force on anybody inside. Very likely pinning them to the opposite wall. One way to do ...
