i still dont think i have gotten any luckier than when i found a dragon mask in a chest early on in my game when i first started playing terraria when it originally came out on ps3.
since it was my first time playing terraria, i was overly cautious, but when i braved up enough to explore the corruption finally, i got lucky to run into the little glitch where the dragon mask spawns inside of a chest.
it gave me just what i needed to fully get used to the game.
unfortunately, i havent really gotten that lucky since then... guess i expended all my luck in that one moment.
