Do you mean influence or direct magickal control? I’ve seen both. I recommend exploring both powers.
Why would you need the skill of influence if you can magickally mind control people? That’s just not how this works. Even if you do put someone into a highly suggestable state or implant things into their mind with magick, you could still fuck up your spell with your own actions, which is why influence is an important skill.
Mind control I think is less popular than the get laid get paid spells because it may be difficult to believe such a thing is possible. If you summon demons often enough, you are very likely to see these things happen even if you don’t outright request for it to happen for a specific purpose. I believe mind control is often integral to the demons’ powers, even if it may seem unrelated to this.
Even if you understand the “theory” behind why this could happen, it is truly a wonder to see it happen right before you, unexpectedly, but so very magickal there is no other reasonable explanation perhaps aside from intense drugging or intensely specific ADHD that just so happens to bounce attention around in a way that is very good for you.
That is something important to realize. Even demonic mind control is still controlling a human mind, and from my experience it will work with the natural mechanics of the human mind to achieve the intended effect. You know how they say that cops have to get tazed if they want to carry one around? The demons will do something similar to you if you choose to go down this path.
