Stained glass is hard because my gem tree farm takes tree years (haha yes much funny) to grow and I can’t be bothered to wait
BoC, yes.Based on my (very) recent experience, I'd say boss farming is better. At least if you really need the money (I haven't found anything to spend it on). Eye and Brain of Cthulhu is probably easy for you if you have good gear. Especially the Eye is easy to craft summons for, as you only need lenses.
Admittedly this wasn't the most exciting, but I fought Brain of Cthulhu 18 times, and ended up with over 1 platinum, plus 3200 crimson ore and 800 tissue samples. Suppose that would sell for a lot as well. Good to finally get some usage out of all those resources I had saved up for 80 hours or whatever
