Right, that's what I outlined in the first post in this thread. The post I was responding to, however, was referencing Eternity Publishing's Immortal's Handbook series - specifically
Ascension - where a character who ascends to being an Eternal and takes the Infinite Strength omnific ability can attempt to move beyond the Ninth Dimension and challenge the Supreme Being. However, this requires defeating twelve guardians who
also possess Infinite Strength, which gives you a flat 50/50 chance of victory, or 1/4,096 chance of overcoming all twelve and making it through. And then, of course, you have to be able to actually overcome the Supreme Being...
