Have you ever sat in an exam and thought to yourself "Damm, I really should have studied"? Well, no more!
By drinking this Essence you'll gain the ability to retcon your own actions.
*If you, for example, have played video games instead of learned for your finals, you could change the action of "playing games" to "learning".
*This reverses the physical consequences as well as your knowledge. For example, this would result in:
*The game reverting to the state before being played. A build chair would revert back into its components.
*You forgetting what happened in the game and how you've felt playing it. You'll still remember the action you have changed, just no details about it.
*Gaining the knowledge you've studied for.
*Changed actions have to be somewhat plausible. Dodging a bullet as a normal human is fine, dodging a nuclear bomb isn't.
*To prevent huge butterfly effects, the changed actions have to have happened a reasonable time ago.
*This power will warn you beforehand if a retcon would drastically change your life.
*It will also automatically change the timeline to protect itself and hence cannot be suppressed, altered, removed, copied, etc.
