"The things you mentioned mostly are. Although turning visible again doesn't add anything - even maintaining invisibility pretty much doesn't except that you can't lose a power you are actively using by loss of generalist momentum, you'd just have specialist invisibility momentum left if you did that. But they aren't big enough. It's better than sleeping but it won't get you to sorcerer level - defined depending on locality as either flight or water breathing by generalist momentum alone. You need big stuff at sorcerer level - landscape-altering things at least every now and then."
