Here is the General guidelines for roleplaying.

Even though it isn't punished, or enforced strictly, your character is a noble in a Middle Ages-type setting. As such, he can't fly through the air, use electricity, and gunpowder has yet to be invented. Your character lives in a world dominated by codes of honour, chivalry, and a limited application of science. Thus, he isn't going to be flying in spaceships, wielding magic, or destroying armies with a single wave of an arm.
None scroll magic isn't really possible in the Battlemaster world unless you're a Daimon. The common words use are, "You are not powerful enough to properly use the magic without the assistance of a scroll" or something similar.
