The Sphere of Spellbinding Might

This ancient artifact from the age Opthelia, known for it cataclysmic battles including all manner of magics and monsters that have since been lost and long forgotten, has resurfaced, potentially due to impending doom or perhaps even as a new cause of it. This supernatural relic allows the wielder to manifest and control arcane, divine, thaumaturgic and psionic magics, while also reducing the material costs and time for casting rituals by 75%. Wielding all four magics is exhausting on the mind/ego for mortal creatures and has the potential to cause minor and in worse cases, complete insanity. It is also an item that can be soul bound through ritual, which can lessen the mental strain, however this process starts a timer that gradually destroys the physical vessel of the user. It has never been discovered what happens to the user's mind/ego and soul once this process completes. Wield at your own risk.
