Ra's Summon.

Summoned Creature or Item: The Mirror of Desire
Appearance:
Description: The Mirror of Desire is a massive mirror that rivals the size of a moderately large building. The Mirror has no power by itself, per se, but when somebody looks at it the true power comes into play. In the reflection of the mirror is reflected a person’s true desires - and they are mentally bound to the desires so they cannot look away even if they want to. Anything reflected by the mirror can have its’ position changed with anything else in the mirror - E.G - An opponent is reflected in the mirror and throws a fireball directly at it. The Mirror’s power will switch the fireball and the opponent’s places - causing the fireball to launch itself directly at the opponent. Another of the mirror’s powers is to amplify anyone who the summoner wishes’s chakra to a massive extent, making even the weakest nin a chakra powerhouse if it is so wished. As previously stated, anyone who looks in the mirror is captivated by their desire, but with tweaking Ra can change this power to entirely dominate a person’s mind at the expense of another’s life - which must be given willingly.
Weakness: The Mirror of Desire requires two owners to summon. Only Ra owns the mirror and nobody else in the universe may own it - this summon is theoretically impossible.
