4 STR, 100 unused AP, 170 required STR for the Empress set... what I remember so far is that I get a total of 32 STR from accessories, plus the 30 from Physical training. Give or take. What should I leave my base STR at?

If you care about damage and are mildly funded, then I'd leave it at 4. Make a 70 cannoneer, that's another 15 str + your 32 + 30 physical training = 77. If you don't have a czak and a htp I would highly recommend getting those both as they make getting the 170 requirement fairly easy. Besides that, try scrolling some worthless items for str and just equip them until you can wear your 140 gear. Then once you can equip it, the pieces should stack off of each other. Also getting some %str should help a lot.
