I had a bit of an embarrassing moment in Terraria. I defeated the Eye of Cthulhu using a gold bow, gold armour and an enchanted boomerang and later on the Eater of Worlds twice. After all that, I found I was one of two demonite bars short of a full set of demonite armour, weapons and tools. To fix that, I decided to beat up the Eye of Cthulhu for a bit of demonite and a gold coin. This time around I had a full set of demonite armour, a demon bow, a musket, a vilethorn and my old enchanted boomerang. That fight was a total walkover, right? Well actually, the bastard killed me before it reached its second phase.
Even though I was playing single player, I was so ashamed.
