Essence ofNerfing

This clear liquid tastes extremely astringent, and gives you the imaginary feeling of someone choking you. By drinking this, you receive the following abilities:

• You receive the ability to nerf yourself if you vastly overpower the setting you are going to (Only nerf, you can’t make yourself stronger than you already are). This can go anywhere from the same level of power as the weakest person in the setting, to the strongest. This is optional, you might use the other abilities of this Essence even if you don’t nerf yourself.

• You can change your power level once every three months. Whatever ability, item, or power in the setting that can measure your power level will always give out the weakest power level you ever had in the setting, but this can be toggled off.

• You can change how your power works, but only by weakening them. You can make it so that an ability that manipulates temperature can only freeze things, for example.

• You can likewise change the power systems of your abilities. For example, making Nasuverse Spells into Naruto Techniques, or Harry Potter Spells into Force Abilities and vice versa. This can be done at any time, and you retain the previous version of any ability you use this on.

• You can likewise do this with items.

• In case you feel you are close to dying, you can temporarily release your powers before the three months pass. This activates automatically for killing blows you can't perceive. After the danger wears off, your abilities return to the previous setting. After this happens, you can adjust your setting again, but the next with a cooldown of six months instead of three (once).

• You you receive the ability to Nerf beings or items that overpower you or everyone else in a setting, by either making them equal in power to you, or the another being in the setting. You can also weaken their abilities in the same ways you are able to your own. You can choose if this is retroactive or not (Be aware that you might irreparably change the story of your chosen world if you make some things too weak retroactively).
