There were two other main resource books for The Fantasy Trip game system: Advanced Wizard and In The Labyrinth. Like the art in Advanced Melee, the Advanced Wizard illustrations were exclusively produced by Robert Phillips.
Arguably, the illustrations found in Advanced Wizard were the weakest of the three resource books, thematically and otherwise, because there were no illustrations of Wizards (surprising, considering the title of the resource book), nothing connecting the subjects to any identifiable milieu, and a complete absence of hot fantasy chicks. We are instead treated to battles with sabre-toothed tigers, does that make up for the lack of the former two?
Various humanoid antagonists make appearances in Advanced Wizard, beating their chests, reaching into crevices, and otherwise posing menacingly.
Many of the best main sourcebook TFT illustrations appeared in the gamemaster's resource, In The Labyrinth. But it seems odd that for a gamebook, wholly devoted to the development of Wizards, there are no images of Wizards. Instead we are provided with illustrations better suited to Advanced Melee and In The Labyrinth, like Conan-esque characters battling Lizardmen and Archers facing off against Giant Lizards.
Robert Phillips' illustrations tend towards minimal environment connecting the subject of the piece to the scene. Take for example the two illustrations below, one of an adventurer discovering an exit from the labyrinth, and another of a guard protecting the entrance to one. There's nothing in the background to connect the adventurer or guard to anything more than a generic fantasy world.
And there's nothing in the text of Advanced Wizard to tie any of these illustrations to the purpose of the resource book. Though the illustrations fit into the broader Fantasy Trip aesthetic, I have to wonder how the editor and publisher justified the inclusion of this particular artwork in this gamebook.
