I'm afraid I may have been enthralled by another. Can you look inside my mind to find out?
This one, I personally don't see much of a problem with. I think it falls under one of the many grey areas that Butcher alludes to through Harry. I don't think the twisting of the mind would really attach. Granted, my game, my rules.
My Ruling: No Lawbreaker. Wardens might disagree.
I've been transformed by a warlock. Can you restore my body?
This one is an edge case. I can see the case for allowing it, but I can also see the case for it being a short slide from just doing it this way to using it the other. Granted, my game, my rules.
My Ruling: Lawbreaker attaches.
I've been enthralled by a warlock. Can you mitigate some of the damage that was done to my mind?
Here, I think the answer is just no, as in, it's not possible. Enthralling damages your brain - the only way that I can recall for True Magic to heal damage to your brain is to stay the heck away from it. If you have trauma from enthralling, it seems that your best and perhaps only way to repair it is time. From what I've read. Granted, my game, my rules.
My Ruling: Lawbreaker attaches.
I need to know how to diffuse a bomb. Please put that skill in my head.
There's no way I can see this working. It falls directly under meddling with the brain. And where you might be able to use it for a while, there are going to be unforeseen side effects from the meddling, the brain is going to rebel and it will slowly drive the person mad. Period. That's not how you learn things. Trying to learn it that way will damage the person and also damage you. I really believe that's how it works. Granted, my game, my rules.
My Ruling: Lawbreaker attaches.
I need you to know how to diffuse a bomb. Please read my mind to acquire that skill.
Grey area. It depends on how you do it. I think rooting around in his brain and pulling out all the memories that gave him the knowledge of the skill would probably hurt him. And writing the memories into your skull would damage you. Now, if you had basically a mental conversation with the person, I can see it falling under the grey area where it's not really that easy to tell. Granted, my game, my rules.
My Ruling: Let's see how you did it, and then we'll talk about it.
I'm learning how to become a werewolf, but my ability to transform myself isn't quite there yet. Turn me into a wolf so that I can practice a wolf's physical skills, then change me back.
I think you'd have the same trauma to the brain as you'd have from non-invited. It's not all a matter of the conscious mind - it's also a matter of the subconscious and even below the subconscious. You'd cause damage that would not be able to be repaired through time. And fool yourself into the path of breaking the Law not being so bad. And, shoot, learning how to transform well is the FIRST thing you should be gaining skills in instead of trying to shortcut through it. Granted, my game, my rules.
My Ruling: Lawbreaker attaches.
I'm being hunted by Red-Court vampires. I need a disguise. Change the way I smell, change my hair color, rapid grow my beard, make me a little taller, alter my cheek bones a bit.
So why are you trying to break the Law when you can use much easier and legal magic to achieve the same effect? Take a glamour, maybe tie it to an object that you wear. Boom. Done. No Lawbreaking. I'm not sure why someone would even do it this way. Granted, my game, my rules.
My Ruling: Lawbreaker attaches.
I lost my hand, help me regrow it.
I'm personally not even sure that True Magic can do this. It seems to be able to help with a lot of things if you're good at that kind of magic, but I don't think it can straight regrow you a hand. Granted, my game, my rules.
My Ruling: Lawbreaker attaches, if you can figure out how to do it.
I have sickle-cell anemia. It's a genetic disease, so it's my "natural" form. Make a tiny change to one particular gene in the cells of my bone marrow, and I'll be free of the disease.
Second verse, same as the first. Granted, my game, my rules.
My Ruling: Lawbreaker attaches, if you can figure out how to do it.
I need to stop smoking. Help me plant a suggestion in my own mind that will help me pause, for just a tiny moment, before grabbing that cigarette.
Seriously, I think this is going to have similar side effects to doing it without permission. Mind magic is complex. You're going to end up putting more in that you want, it's going to do brain damage, there's going to be side effects and the wizard is going to end up thinking that doing that isn't so bad and starting his own slide into the Lawbreaking and the devolution into a Warlock. Granted, my game, my rules.
My Ruling: Lawbreaker attaches.
I'm more or less a hardliner for the rules. There are grey areas and I realize that, but a lot of things are just straight out to me, no matter if you have permission to or not.
Edited to Add: Rulings on each case.
