I like the glamour bard right now.
Essentially, it is "Rock Star" the power. Anything you can imagine a Famous Singer in this world convincing a massive fan to do after a performance, this college can pull off on anyone.
Honestly, I think the most powerful ability is the fact that not charming them with the performance doesn't let them know you tried to magic them.
I do agree some of the language needs tidied up, but it looks good to me, and makes a very powerful enchanter.
The Whispers
The frighten ability needs to make two things more clear. 1) Are they scared of the bard too? (My assumption is yes, but a light touch of friends may make it not matter) and 2) the running and hiding is if they are left to their own devices.
Let's say you have someone your buddies want to interrogate? You just need 10 minutes and they are so scared all they want to do is hide in a dark corner. Now you've got them in a position where they will tell you things. You've given a gang's Lieutenant fear and paranoia, and Rary's Telepathic bond. Now as he flees, you keep up the pressure, paranoia, paranoia, are you sure your boss didn't want you murdered, are you sire you can trust him, you should strike before he does, ect. You the bard have done nothing, even better, you might not have even been seen with them but they attack their boss.
Actually, another thing we may need a clarification on is what happens after that hour is up. How do they perceive the bard and the last hour?
Mantle of Whispers is stupid good, because nothing says you can't use the same shadow multiple times. And it only takes an action to refresh. You can kill a someone innoucous, take their appearance and as long as you can find a handful of seconds every hour to refresh it, you could pose as a bodyguard during an important meeting, maybe get the boss alone and fear him into running out and leaving you in charge of this very important meeting.
This is really shaping up to be one of the ultimate intrigue classes of the game.
