HP can be raised from 390 to 410, 430, and 450 with scrolls of resistance (+20hp for each piece of equipment). This will replace the virility scrolls if you added them previously, however raising HP isn't necessary because 390 is already more than enough for pretty much all the opponents, while not really changing much for the cursed opponents, as they use your HP fast, you'll need orc's favorite dish or whichever dish you use anyway.

Focus can be raised from 30 to 40, 50, and 60 with scrolls of focus (10% for each piece of equipment). This replaces the others again, so you can pretty much only use one stat boost if you use the same scroll for all 3.  This one isn't necessary either and 30% is enough if you don't have trouble hitting the middle of the target when attacking an opponent.

If you want all 3 raised equally, you can add 1 scroll for each stat on each piece of equipment to get 137 Virility, 400 HP, and 40 Focus.
