By consuming the essence of timelines you will get a few boons
*First you gain the ability to split your timeline into as many parallel timelines as you want
*you will also get a scaling ability to keep track of all your timelines as well as the ability to act independently in all of them
*as long as you're alive in one timeline you will never truly die
*you can also decide if the timelines can interact with eachother or not, this works on everything below the level of archdeity, Ein sof, supreme god, etc.
*Yes this does mean that you can link them to such a degree that strenght gained in one carries over to all other ones
*you can also change how they interact with each other at any moment, not only during their creation
*you can also control the characteristics or your timelines, for example how fast time moves relative to your other timelines, when it starts (max early start is from the moment you drink the essence), and so fort
*if you have more essences' you can choose which essence applies in which timeline as well as how they manifest (if said essence can manifest in more than one way), an essence can be used on as many different timelines as you want.
