What Wish is to a mortal spellcaster, Absolute Will is to the gods. Absolute Will causes the instantaneous fulfillment of whatever desire the caster specifies at the time of casting. This spell can only be cast by one who has achieved godhood or killed a deity in some way, shape, or form. The desired effect of Absolute Will is specified to the spellcaster's meaning and implied will, so it cannot be loopholed by the DM the way Wish can. The effects of Absolute Will can only be countered by another Absolute WIll. Any spell or action to the contrary of the Absolute Will instantly fails.

When Absolute Will is cast, the spellcaster, mortal or otherwise, is instantly demolished. The caster's very essence is used as fuel to cast the spell, meaning once the spell is cast, they will simply no longer exist. No form of resurrection can be used on the caster, except for another Absolute Will. People viewing the caster while the spell takes place will briefly see the Astral Planes bend around and converge upon them, then shatter, then reform to what they once were, only now the Absolute Will's desired effect having taken place and the caster no longer existing.
