So umm there are a few locked/deactivated items and i started unlocking them with the first being Eric's Ring.
This item is for entertainment purposes only, and you cant play an actual serious game with it because it gives you 2000 damage and 10000 health, and many other buffs like attack speed increase etc.
Here is part of the text inside the LUA file written by the developers probably:
############################################
# Eric's Ring - Not used in game.
# For debug/testing.
############################################

You may think it is useless but it is not, because just seeing that not only you, but also the AI buys it from the start, makes for a really HILARIOUS GAME! 
Try it and have a good laugh! Just make sure you are not eating while doing it because you might spit in your keyboard accidentally 
The item did not have any price set, so I gave it 15000 gold, just to make sure that people will use it in Single player, or In having fun with some friends online. It didnt have a buff description either so I had to write it down and copy paste some stuff.
the tool tip saying "Never gonna give you up, never gonna let you down." was written by the developers actually. I just left it there, was kinda heroic/funny.
Anyway enough of my dull blah blah blah.
