Every single aspect of your powers, strength, and perks can be selectively toggled and dialed to the point they can be turned completely off. You can also select people and individuals who are not affected by your perks and powers, making it seem as if they're capable of withstanding reality-breaking attacks. You can scale your reality-ending destruction to be tuned down to cause mild concussions, granting you the ability to not overkill everything in existence. As long as you wish it, It’s almost impossible to kill someone if you don't want to.
This does not work on drawbacks or on perks that rely on items like Wealthy.
