sniff I sense someone waiting for the next Terraria State of the Game. I also sense the feeling of doom as you enter Infernum Hardmode. As someone who has gotten to Post Moon-Lord Infernum, all I can say is DONT GIVE UP. The bosses may get insanely difficult but trust me. You can and WILL prevail. I would recommend you try beating every boss, as the optional boss's drops can easily help you out a TON.
