Ordeal of the Magic Tower

From publisher blurb:

Four young wizards-in-training. One impossibly difficult task: move through the six ever-changing levels of the Magic Tower in Sphilix’s Sorcery School, master your cantrips, and craft your magic wand! Will you become a full fledged mage, or succumb to the dangers that the Archmages have in store for you? There is only one way to know… accept the challenge, and survive the Ordeal of the Magic Tower! This is a procedural adventure for apprentices. It contains rules for 12 Cantrips (zero level spells). Only the core Four Against Darkness rules are required to play.
