I'd like to suggest adding Template:Infobox instead of that table. The box still needs an update of your design and the necessary information, but it would be much easier. Encredechine (talk) 09:00, 8 June 2017 (UTC)
I can't seem to find a way to edit the categories in the infobox. Right now it is limited to the already present categories, which are insufficient for usage here, and I don't know how to change them (though I see examples of different infoboxes so I know it's possible).

- A wild guess, but I think after that last |} in the infobox, you'll need something like
{{#ifeq: {{NAMESPACE}} | Template | | <includeonly>[[Category:Items]] {{#if: {{{tech power|}}} | [[Category:Tech Power Items]] }}</includeonly> }} Encredechine (talk) 08:45, 12 June 2017 (UTC)
