Hat prices are to offset people getting too many shillings. Rather than give you too much choice to spend everything on, they set the price high so you use your shillings up faster. I’ve got 2k now sat doing nothing and won’t get any of the new hats so next time I’ll likely have 3-4k, so expect the next lot of hats to be roughly that price(3.5k).
STILL better than RNG hell in Comm chests for hats.
