Price checks go in the Bazaar forum. So you might move this thread there (by editing the original post and choosing that forum from the drop-down menu).

As Fehzor said, this is a very good shield. Shock, fire, and freeze are the best UVs you could hope for on a shield. They're so good that Punch doesn't give them.

We can't answer whether you should sell or keep it, because that comes down to whether you value the shield more than other players do. We don't know that, because you've told us nothing about yourself. For example:

* Are you an extreme end-game player trying to accumulate the very best equipment? Then keep it. This is close to the best possible shield in the game.

* Are you a novice-to-intermediate player who has lots of equipment to acquire? Then sell this and use the profits to buy a bunch of items.

Pretty good.... unfortunately there aren't many Pierce enemies that deal shock and one of them (the Quicksilver) is also capable of elemental attacks. Regardless the status resist will help out in shock levels more than a regular BTS would.
