Fiancée needs name of old RPG

My Fiancée who has just recently gotten back into gaming a bit has a fleeting memory of an old school isometric RPG. From what she has described I don't believe it is not Ultima and it certainly isn't Wizardy so I am thinking that she may have played one of the Gold Box games. Clairvoyance is a spell that you can cast... with your mouse apparently. It was used to find hidden doors. 
 
 Forgive my recounting because she is giving this to me through the fog of many a glass of wine. 
 
There was an initial dungeon that when defeated yielded an amulet of unknown purpose. When returning to the starting town after the initial dungeon you find it burning and a trail leading.... west. The graphics were somewhere between Ultima 4 and 5 from what I have gathered. 
 
Please help me, my knowledge of old school RPGs is exhausted and I know someone around here has played this game. She wants it again. 
 
Edit: Apparently you might not need your mouse to play Clairvoyance.

Why do you call your hand a she?

League of Legends was a Iso I think and had that spell....

Old RPG as in maybe early 90s Computer RPG. Probably not CD-Rom.

Defiantly not CD-Rom apparently.

Try the Can't remember the name of this game? official thread :D
