I reached level 14 and the lumber mill and spent a little while carefully getting all my people into position. Once reach, I attacked. Red Prince, my Knight with the highest physical armor, got all his armor and half his health stripped on one turn from a single enemy.
I guess in fairness the last time I went on a major shopping spree I was level 11, but I've picked up some stuff since then.
Time to go shopping to replace all my gear. Or more accurately, time to go shopping, then leave the game running for an hour to see if merchants have stuff worth buying to fill up the rest of my slots. Repeat as needed.
I think I also need to boost my Knight's INT to 14 and my Mages's STR to 14 so I can wear the opposite type of chest armor, because mages get ridiculously little PA just using INT-requiring gear.
