Final Word Broad Sword; "Concluder" - Level 26 Unique Weapon

On page 105 of the original Unearthed Arcana, you will find the description of nine potent blades, forged with magics that make them of incredible value to even the most potent warrior. As I am intending to throw a few nice bits at the players in my up coming Stag Weekend game, I thought I would convert them (or at least one of them) to 4e. Here then, is the Concluder.
