Allow True Strength to grant entrance to the Chaos Plane
Allowing a Paragon ULE to be possible
Acquiring the Crown and Medal of Chaos for any ultra ending is a chaotic act - making being both a Paragon of Order and an Ultra Ending mutually exclusive.
Due to the difficulty of achieving True Strength, I don't believe having True Strength as an alternative to the Medal and Crown of Chaos will imbalance the game, or cheapen an ultra ending. Instead, I think it would be a good addition, to grant entrance to the Chaos Plane as a Paragon, making a Paragon of Order Ultra Lawful Ending possible.
