From publisher blurb:
Use transmutation magic in character development, worldbuilding, and adventures!
The magnum opus, or Great Work, of alchemy is the transmutation of base metals like lead into precious metals like gold. This is arguably the foundation of alteration and transmutation magic in fantasy roleplaying. The ability to turn one thing into another, even temporarily, can be both useful and frightening. Alteration also covers manipulating things, changing their shape without making deeper modifications to their basic properties. Objects can be made larger or smaller, stronger or weaker, as the caster desires.
Antagonists will seek to leverage the same abilities, albeit for darker and more self-serving reasons. They won’t use alteration as ethically as a protagonist might, if they consider the ramifications at all. They will use this category of magic to play at being a deity, tampering with what the gods have created, warping and distorting the natural order of things to suit their whims. The materials they manipulate will be put to use furthering their own causes.
As with all magic, there will be some fear and misunderstanding among the common folk. The title transmuter implies that the caster bend any material to their will, even animating it. Such casters will face resentment from those who feel such power is innately unethical, no matter how it is used. Many people will fear that their own possessions might be destroyed or used against them. There may be a great deal of distrust if alteration and transmutation magic is used in the open, even if it is for helpful purposes.
In this book, we’ll show you how to utilize alteration in your worldbuilding endeavors. You’ll see how it can influence character, setting, and story elements. By the end, you’ll understand how to make alteration into an essential, useful, and entertaining part of your campaign.
