I feel Zalk's sword doesn't really count, it's not supposed to be part of an "ordinary" item curve. It's a hidden reward you get for making the effort to kill Z despite the game and the power discrepancy telling you not to try, more like an Easter egg than anything else.
It's also not the best weapon, Tyr's sword for example is a better choice for a two-handed fighter.
Ok. I'll agree to that except Tyr's sword. Unless they increased it's power, I didn't think it dealt more damage. I like it, mind you, and my Cleric of Tye usually wields it at level 4, but I thought it didn't do as much.
