Another point: Arent potions specifically limited to the individual who drinks it?  Meaning you can't drink a potion and suddenly the entire group is invisible.  The potion would have to have enough uses and you would need enough time for every person to drink it.  A blanket veil effect seems more like a standard enchantment item.

I'm fairly ambiguious about when my campaign takes place (after Grave Peril, before Changes), so no it doesn't really affect my scenario ideas.  I can slide the canon into my game pretty easily thus far thankfully.

I'd add in this:
-Magic comes from within you as a manifestation of your beliefs.
-Healing with Magic takes just as much effort as healing via mundane medicine.
-Many supernatural creatures out there. Most of them way stronger than he is. And they consider him prey.

Beat me to it.  The first thing it to get him to understand how healing magic works in this game.  I could see a nightmare scenario where the player thinks he can just wave his hands around and heal the groups consequences mid combat instantly. 

You can do some really neat stuff with healing magic, but most of it seems to be pre and post combat, not during.  Make sure he understands that.  Beyond that I would just give him a basic run down of the major factions.  Vamp courts, denarians, outsiders, white council, the sidhe courts, ect.  The details can be given to him as needed.

I'm pretty sure that this is not true.  Or mostly not true (scene aspects, city aspects, theme/threat aspects, etc. blur this line).  I'm pretty sure that one character cannot be compelled on the basis of another character's personal aspects.

They can, it's just not particularly common.  A character, PC or otherwise, can invoke or be compelled by any aspect they are interacting with.  The source of the aspect doesn't matter, as long as it makes sense that the aspect would affect the action being taken.

Yeah, the intentional hexing rules are hella broken.  I insist on charging stress for those kind of shenanigans at my table. 

A wizard having his own toys fail = compel on the wizard.
A wizard trying to destroy something offensively = a spell as normal.  (When this occurs, I may also compel a bunch of other stuff/people nearby for other, unintentional hexes, but I consider it like compelling a scene aspect at that point.)

Me too, if it's during a conflict at any rate.  Intentional by RAW is basically a stress free magical maneuver that you don't have to roll for.

Outside of combat I don't really see a reason to do so though.

I like the idea of an Outsider and Lash warring inside Harrys head.  Though there's a bit of an inconsistency in that idea.  It would mean Lash would have to be ignorant of the Outsider for the several years he was in Harrys head; which I just don't buy.  She would of known about another entity in his head the second Harry touched the coin.

Fixation? He only posted three times, I wouldn't call that much of a fixation.

That aside, I'm not a huge fan of Stone Sleep. It ties consequence recovery to in-game time, which is dangerous territory. And on top of that it has vague mechanics for damage inflicted on sleeping gargoyles. And its usefulness is heavily dependent on the narrative situation, so it'll be really powerful in some games and crippling in others.

So while it's hardly an awful Power, it's far from perfect.

I'd prefer Recovery linked to Human Form or Limitation plus an Aspect. More balanced and more elegant.

PS: Stone Sleep would be pretty funny in a South Pole game.

Yeah that was me haha, and I'm still not convinced about it as a PC, mostly for the reasons above.

If a player really wanted to, I would do my best to come up with a happy compromise.  Though i admit my opinion is colored by my own game and players.  We have had plenty of all night sessions where only 2 or 3 hours of game time have passed.  If these happen to be during the day, then that one player is just out the entire session or I have to rush the other players through daytime scenes.  Which is not something I'm willing to do for of 1 of my 4 PC's.

I think my view on it also stems from an issue I've seen and talked about with other GM's many times.  When a player comes up with an interesting idea, but doesn't stop to really ask themselves "Will this character actually be fun to play as for months or even years?"

I ran into this problem when I first started going through character creation for DFRPG.  A potential player repeatedly gave ideas for his character that would constantly make it difficult to interact with the character in multiple ways, and by extension the player himself.  I tried to come up with compromises, but he wasn't willing to bend.  He ended up not playing.

I think it's also important for players to also ask themselves "will this character hinder or force the GM and other players to play a certain way to accomidate my character?"

Based on what you have been saying on this thread, my one biggest suggestion is this: you keep talking about the way you and your players are "used to playing", so my advice is to ignore all of that.  Accept that this will be something very different and let your players know that ahead of time.  Forget the way you've been playing and take it as a new experience.

Once you and your players get used to the core system of the game, then start pulling on past experiences as inspiration to enhance the game for both you and your players.

As for the meta-interaction between players and GM, you can mostly keep this in game if you want.  All you really need to do is announce Concession, then continue to roleplay.  Just let players know before you start your game is that what happens in your "Concession phases" must stand.  This should work fairly well since you said you have played with your group for years, so you should have a good idea of what they would accept as a good Concession and vice-versa.

I honestly feel you're just over thinking the whole situtation instead of just rolling with it.
