I'm glad you saw it that way, because FF14's crafting system was a big inspiration! I was going to create several skills that made the stats go up in uncontrollable ways so that you had to carefully plot out a skill rotation. For example, increasing size would also increase other stats, and then have skills to lower them as well. Sadly as I mentioned in the comments, time got away from me so I had to reduce to 2 stats (even if the others are programmed in the game but do nothing) to get something running until submission time.
Thanks for the kind words!
