Iratha's Cord is very useful, even for a stand-alone item. It comes with solid defense and increases your minimum damage by 5, acting as a small version of Bloodfist.
The potential of the item is shown when the user has collected 2 pieces to this set, the belt then gives the wearer +10 to Dexterity.
