Why you stick to this cornercase of trying to hurt a loved one?
@Samasboy1: If you are still reading this, charm person is not an evil spell. It´s a high magic world and things like that are pretty common. However if you use it to get someone into bed who normally wouldn´t do that, it´s abusive and there could be repercussions afterwards. And if you are seen and identified casting a charm spell on someone it could be problematic too. That´s a difficulty the magic system forces on social casters. Suggestion or hypnotism might be better spells in this case, especially hypnotism which could be sold as a show and eventually protects yourself from consequences by the victim.
While the subject is fascinated by this spell, it reacts as though it were two steps more friendly in attitude. This allows you to make a single request of the affected creature (provided you can communicate with it). The request must be brief and reasonable. Even after the spell ends, the creature retains its new attitude toward you, but only with respect to that particular request.
I see. Well such cornercases are unimportant for me.
I´m glad we and many others could at last agree on how charm functions most times, which is kind of an important thing considering PFS and "table variation".
Maybe it would help to think about it if we were the ones that were charmed into dropping trou.
That´s why you keep some charm spells all times, to "re-charm" your teammates. Makes up for a interesting situation hehehe, just like out of a comic. Two sorcerers standing next to a fighter double CHA checking him, untill you rule only the latest charm works.
One charm to rule them all?
Well opposed Charisma checks. Being charmed / dominated by your allies can be really, really beneficial if you trust them.
So, you don't think their mind being changed such that they offer free aid and assistance to a potentially former enemy undercuts their free will?Oh, it totally does. Which is why GOOD spellcasters should only deal with enemies via less morally problematic methods, like burning them to death or stabbing them with swords repeatedly.
Everything's good when you do it to bad people!
He who lives by the charm dies by the charm?
I've used charm as a way to gather information from prisoners. Basically let someone else capture them, cast charm person and then come in. They're essentially your ally and with a little RPing you can get most information out of them.
In fact, if you plan it correctly you can set up your spells for the day to essentially guarantee they fail their save eventually.
Of course depending on the situation surrounding their capture and the spellcaster's role in it, the DM might want to put a bonus to either the save or the attitude. I mean, if the spellcaster injured or in some other way seriously affected them, then charm person might be less effective or ineffective.
The best analogy i can come to with charm person is the way people open up to the Doctor in Doctor Who. More than one character in the TV show has remarked after telling the Doctor something confidential that they have no idea why they would tell a complete stranger something so personal.
Just my 2c
In both cases, would the person remember what they were asked to do (Charm) or forced to do (Dominate)?
This is a staff. You can use it to lighten your burden, to defend against attack, to guide the way, to bludgeon someone to death, to use as a splint, to destroy the possessions of others. This is a staff. The staff does not make choices, but your choices for the staff make you.
