OK, this is a Bioware item bug. The properties of the item are as follows:
Attack Bonus +2
Attack Bonus vs. Racial Group: Undead +3
Light Low (10m) White
While it does have 50 charges, there's no powers associated with those charges.
So while it's kind of funny, it's one of Bioware's default items and short of re-making it to remove the harmless charges, there's not really anything to do here. There's no powers that are missing or anything.
So it's a bug, but not ours, and there's nothing for us to put in place to use those charges, so I'm going to go with: It's working as intended.
