OK, so after I got the requisite armor and weapons I took on the Wall Of Flesh.... which was a hard but fun battle..... but now my world hates me. It's rate of spreading corruption has increased and some extremely nasty monsters have spawned on my world.... for which I had to read the wiki and find out I need to create different ores to make MORE and better weapons and armor. And apparently I have to take on new bosses now as well. This is all well and good, I enjoy a challenge in my games, but the difficulty meter now that I've changed the world by beating the Wall has just risen over 9000, and now the world inevitably kicks my ass every time I leave my treehouse door.
