Illusion spells often become nightmares for Dungeon Masters and players alike. While illusions spells hold out the promise of cool possibilities, they often prove disappointing because of the difficulty in making them work effectively within the game mechanics. Players often find them to be unreliable, useless, or something that bogs down a game in debates.
This work is aimed at restoring the dream by providing a practical guide to using and running illusion spells like Major Image. As much as possible the guide sticks with RAW and gathers answers about rules questions from scattered sources into one place.
But this work goes beyond RAW to add to the game by providing new uses for illusions and some clarifications.
