Hey Bud. I been searching for this one ever since it first came out, and I'm still comin up short. But don't get too discouraged. I'll look around a bit, and let u know if I find anything. (PS I found your post in my search for the game!!)
I found a link that works.

It is a LEGAL abandonware that is free to download. The gameplay is similar to Diablo, but with Magic Duels mixed in. The sys reqs are nonexistent. It was made 4 win95. The only glitch I've found so far is that you have to load the RPG thru the main loader titled Magic.exe. The RPG portion is called Shandalar. You click "World" in the main menu, then click "Shandalar," and then you have to create your char, click save, then leave, and after that your playing.
