Mirror of Potential

Appearance
The Mirror of Potential looks like a mirror with ornate designs of many races around its edges, often with weapons or tools of civilization in their hands. It is kept in a highly polished state at all times.

The Mirror of Potential can be used to make those who look within take a test and if they pass it then they gain use of all of the power that would have gained by training. While taking the test, they are completely defenseless as taking it requires their full attention at the cost of being at the mercy of others.

This power does not affect gods and they can only take the test to amuse themselves for a short while.

By the time that the Second Age comes around, it is known that the children of those who pass the test gain a power in addition to those of the base race's, making them far more versatile and powerful than those who ddn't have ancestors who took the test.

History
The Mirror of Potential was used to make every single one of Mina's heroes more powerful for the rigours of the First Age. By the time that the Second Age comes about the Mirror has become naught but a myth, however many still search for it to gain power.

The part that they don't realize however is that the Mirror had became nothing more than the equivalent of a playtool or vanity mirror for Mina's Pantheon.
