So, do you know about the Power Ring from Green Lantern? The Quantum Bands from the Quasar?
Thinking of that, what if there was an object similar to these ones, but they are fully created to you? How it would be? What type of object it would be? What powers would it grant you while you are using it?
Note:
Please, don't create Almighty Objects (like Infinity Gauntlet, Cosmic Cube, etc.), so no powers that are Almighty, Absolute, Omni, Meta, Transcendent, etc.
But, it can some "normal" power, but powerful, like Telekinesis, Energy Manipulation, etc., not Nigh-Omnipotence, Metapotence, Wish Granting, Reality Warping, etc.
