I have a question, I know how Jenna can upgrade my stuff but I kind of skipped the part where you get specified things, like Fine Lean Meat, or is it just by fighting enemies to get them.
Enemy drops primarily yes. The rarer items will also become more common as the game progresses. Hole in the ground has more opportunities to get drops in the gauntlet or parlor mode options
I have notice that a IntraSystem book but you should also try adding a bestiary so people could look into finding specific materials. So I hope this suggestion will help with gameplay and grinding.
Something I have and will consider, whether in the walkthrough or otherwise. Though I'll likely do so later in the game when enough of it is done for me to be comfortable reassessing all the drops and updating those at that point.
