Ring of Erasure it's a obscenely powerful artifact that has the power to erase virtually anything.
Powers:
1st Existence Erasure: on conceptual level if i stand for example close or even interact with anybody regardless if i do it via talk or direct physical contact somebody i can erase anyone and anything who has/is composed of/uses the same type of energy as that person/individual this works in the entire verse the only ones immune to this power of the ring are the wearers of the ring and true Omnipotents.
2nd: Nonexistence.
3rd Erasure Empowerment i gain power level intelligence and other stats by a factor of 30 and the multipliers stack up permanently when i erase someone/something so i still grow up at a insane rate.
