The Dungeonmaster (1984)

The Dungeonmaster (1984), also known as Ragewar, is a low budget sci-fi flick about a computer whiz named Paul (Jeffrey Byron) who spends more time on his computer than he does with real people. Paul discovers that he has been selected to participate in a battle with an evil wizard named Mestema (Richard Moll, best known for playing Bull on Night Court), and after having his computer transformed into a wristband, he enters a world where he must do life or death battles with a series of monsters! Gina Calabrese plays a particularly challenging adversary who challenges this computer nerd with the ultimate nerd challenge: A naked woman! Gina goes fully nude, baring all as she seduces Paul into following her, and when he gets her on a bed, a group of monsters come and attack him! It looks like The Dungeonmaster has turned you into a DungeonMaster Bater!
