The Forbidden Technique

There are many techniques/spells throughout the world/multiverse, and some are hidden/forbidden to be used due to either repercussions from using them or the power they hold if someone was able to use them. At least one such technique has been discovered and now you have that power to use it as you please.

The question is: what is the power?

Is it the power of acceptance? People will accept your actions no matter what they are or whatever you say is accepted as fact.

Is it the power to corrupt the mind? Mold and morph a mind to however you want

Is it the power to edit the world? Change things from minor to drastic without much effort

Is it the power to change reality? Don't like how life is then mold it to your will

Is it the power to form binding contracts? Watch out for loopholes

The power to change what is common and not? What was once insulting can now be complimentary

The power to induce sexual desire in others? Let's see the hot people ignore you now

The power to influence people's thoughts? Change the mind and change your fortune

To transform people into your slaves? Always fun

Hypnosis/Mind Control? An oldy but still goody

Summoning people to serve you from other dimensions? Don't need to leave your world to enjoy

Rule making? If the rules don't suit you, then change them

Imagination and reality? From your mind to becoming real

Magic words? Say the magic word(s) and people do what is desired

Turn people into pets/creatures/servants? A genie here, a elven babe there, a gnome over there, etc etc.

Summon a being to grant your desires? Demon, Fairy Godparent, Genie, Wishing Star, or something else

Become an overlord and corrupt beings into your slaves/soldiers?

Mixture? You got more than one power, but maybe it's not that simple as it could be that the power changes after a certain amount of time or uses. You got hypnosis one moment and then you have the power to form contracts the very next.

There are many options and powers out there that could be what you have discovered and many routes to take once you've gained said power.

So what's it gonna be?
