I've a guide request: item upgrading.
I've not really seen a comprehensive how to on this. Questions like:
What changes happen each time I use the nanoforge?
How many times can I upgrade?
How do nanoshards factor in and how to best aquire them?
What upgrades/effects can I expect from the 3000?
How are mods affected?
Best strategies for upgrading and what not to upgrade.
There are bits and pieces laying about the web on the subject, like use limits listed here, but it's a chore to track them all down and some of the info has been outdated by patches. And some of the finer points really aren't covered that well anywhere at all.
