Baleful Gem, etc.

One thing that would be nice is if the spear were an actual item that we could use. I mean it was a weapon for the guy we got it from, apparently a pretty good weapon to boot, so it would make sense that we could stab things with it.

Give it some set qualities like a unique, and some random properties so it could be "good" or awful. Lock it to our character as a quest item, and if I happen to get a randomly rolled good version of the item I may just hold onto it long term.
