. "A spell's MP cost is equal to its level, e.g. Fire 8 will cost 8 MP. Thus a spell can cost anywhere from 1 to 16 MP, and in certain cases, a higher level spell is economically disadvantageous as it brings about marginally better effects at a higher cost. Should the need arise, characters can discard spells to make room for new ones. Once a spell is deleted its gained skill levels and experience will not be retained. Characters can use the Tomes directly from their inventory to call on a spell's intended effect with moderate power but this function is one-time use and the Tome disappears after used in such a way.
