I'd suggest you skip some of the basics and assume that the people using the walkthrough have already beat the game at least once. As you said, those who try the 4 White Mage challenge are most likely familiar with the game already. However, boss tips could still be very useful, and the same can be said about level suggestions, so the gamer gets some kind of an idea about how much leveling up is required to survive the following dungeons with the White Mages.
