From the back cover:
When spells and lightning bolts won't do the trick ... wizards get down to the nitty gritty of Duel Arcane.
In Duel Arcane, shapechanging mages engage in individual combat, using the forms of legendary and mythical beasts. The game is fast moving, with lightning quick shifts of advantage, as the players transform themselves from animal to animal. Fight as a leopard, a manticore, or even a griffon -- vanquish powerful arcane foes on the road to being the most powerful wizard alive !!
Duel Arcane includes a 28 page rules booklet, 4 pullout character sheets, and descriptions for over thirty different animals and beasts of legend and myth.
So conjure up a few golden coins, and let the duel begin ...

(The game consists of a booklet of rules, charts, descriptions and options, plus character sheets. It's very similar to the combat system of a typical role-playing game, but without the roleplaying element.)
