The cover art does not do justice to the contents, for here is an inspired adventuring concept, the wandering artist in search of inspiration, written up as an entire character class. In a way, it is taking the bard class and retooling it away from 'performance' to 'creativity' yet this is something distinctive of its own.
Wandering artists have limited arcane spell use, but their real power lies in developing their artistic talents, learning new techniques for their chosen discipline that confer power and abilities (as well as making their artwork better!). Such characters are on a true journey through life, seeking to perfect their art as well as gaining inspiration from everything they see and experience.
Each wandering artist must choose a discipline, the precise form his artistic expression takes, and which he focusses on in an almost obsessive manner. Each provides related spells and other abilities as the artist rises in level, making them distinctive as well as potent adventurers. These disciplines are wide-ranging covering craft skills as well as purely 'artistic' ones: basketweaving, brewing, cooking (ah, at last I can play a wandering chef without having to pretend to be a rogue or ranger at the same time!), metalworking, origami, painting, pottery, scrimshaw, sculpture, tailoring, tattoo, textiles, and even writing are available - each with a fully-developed list of the techniques that can be mastered.
A spell list and a few new feats round this out, but it blows a refreshing breeze through adventuring as a concept... at least you know WHY the wandering artist is in the party!
