Forgemaster:
Also, since these are devices can analytical heroes make one of them without actually picking that power set? It feels weird but analytical hero even allows building of magical items (albeit with heavy penalty). This also implies that anyone can make a super-invention or magical items without picking hardware or super-invention power set if they can mitigate the skill penalties. Am I missing something here?
Yes, you are missing something. Only the hardware or super-invention categories allow skill percentages to advance beyond 98%. Outside of those categories, the ability to make a magic item is 0%, which means it's impossible.
The Natural Genius is more a planner than an inventor. That power category, to me, appears to be more akin to Egghead than Tony Stark. Or, you could say it's more like Gru than Dr. Nefario. What you're probably looking for is Super-Invention. Of course, the beginning it would be limited to technology because the ability to create magic items would be mega-heroish. It would still allow you to build and wield ETHODAD.
I've decided, as a quick ruling, that each super-invention can contain a maximum of one major or two minor powers. The number of inventions will be determined by the number of powers:
number of powers | possible number of super-inventions |
---|
One Major or two Minor | one super-invention |
One Major and one Minor | two super-inventions |
Two Major | two super-inventions |
Three Minor (no Major powers) | two super-inventions |
One Major & three Minor | three super-inventions |
Four Minor | two super-inventions |
Two Major and one Minor | three super-inventions |
Two Major and two Minor. | three super-inventions |
