User blog:ElsaRules!!!/Need an Artifact

I'm in the process of writing a book, and I need a bit of help from everyone.

In my book, a situation arises where I am trapped in my subconscious, which I eventually manifest into Warehouse 13 in order to find an artifact to help me. The goal is to use an artifact whose properties increase my focus and/or determination, allowing my subconscious need to escape and the belief of its power to give me the power to escape my subconscious temporarily and destroy the cause before I'm trapped again (It's a story; it doesn't have to make perfect sense).

I had considered Bobby Fischer's Bag of Marbles, but I thought there would be a twist where it is not there and Mrs. Fredric takes me to another artifact that can help. What I need are ideas for artifacts similar to the Marbles in their effect, or an artifact whose effects will lead to the same conclusion (maybe mental protection or something?). Any ideas?
