One patron asked for a wizard subclass that replaces spells with technology that does the same thing, controls constructs, and can even work where there's antimagic areas.
I thought about this for quite a while and came to the conclusion that all that that could be accomplished by reflavoring existing game mechanics and maybe providing a custom spell and magic item.
Using this reflavored wizardry as a base, anyone can use the ideas for all manner of technomagical stuff.
