Wizardry 2 was released in 1982 by Sir-Tech Software on Apple II. I'm playing the MSDOS version here. Note that you need to transfer your characters from Wizardry 1 as there's no possibility to start a fresh team on Wizardry 2. Also one of your mages has to be level 13 in order to be able to cast the spell MALOR as it's the clue to get from Floor -1 to Floor -2.. This is game number 4 for me.
