Plenty. I never made a list. Suffice to say, almost everything that's hexed has many drawbacks.
I always got everything identified in full, then sold whatever was hexed. Because I had plenty of points in haggle, I got a very good deal for 'em.
Beware especially of any sword you find lying around in dungeons. There's one whose name I forget that's not merely hexed, but causes permanant loss to dexterity after being equipped. There's no cure, and the bug was never fixed in the patch.
To the Righteous belong the fruits of violent victory. The rest of us will have to settle for warm friends, warm lovers, and a wink from a quietly supportive universe.
