A game on the Proving Grounds that I, as far as I know, invented myself - Only stacking Trinity Forces, not even boots are allowed.

While I made a mistake by doing it at the Public Beta (which means there were like two or three people who actually stacked Trinity Forces, while the rest bought whatever they felt like, instead of Trinity Forces and me asking to sell their items and buy Trinity Forces), I already found it a lot of fun.

Just wanted to make this blog post to tell others about a good idea by the way.
