Aldur's Watchtower - The 350% Enhanced Damage is on the complete set, not on the weapon. Enhanced Damage from non-weapon equipment works like Enhanced Damage from skills and the strength bonus, which is different from how Enhanced Damage on the weapon works. Essentially, the 350% ED will add 350% of your weapon damage to your total. With a 60-93 damage weapon, that means the 350% Enhanced Damage will add 210-325 total damage. This is really not very significant, but it's not a bug, just a balance issue.
