As an alchemist, your goal is to solve a series of mazes and prove your worth. To do this, you must transform the items you find in the maze into more useful objects. For example, a piece of iron can turn into a glass key when dropped in a pool of fire. You'll need to collect these items and use them to overcome obstacles like glass doors.
The twist is that some transformations require multiple stages, and not all transformations are random. If you keep good notes, you'll be able to figure out all the possible transformations. But watch out - there are monsters lurking in the maze that will try to stop you. Fortunately, transforming something into a decent weapon can help you fend them off.
