My answer to the question "what do you need at minimum to beat Terraria?". More for academic example than actual gameplay... because it would be miserable to finish. Pictured is everything you get. Master difficulty. More details on the Steam Workshop page. Questions? Disagreements? AMA.
EDIT: Tweaked it. It's much easier now. Updated picture as well. The problem was that you would have had to kill a mech boss before being able to smelt ingots or fish. That didn't sit right with me. The difference? I added 1 stone and 1 granite.
