Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

So I'm doing a bit of an upgrade with one of my character's equipment and I'm trying to decide between two items. The specifics are not too important, but both give a little bit of damage reduction. The first gives 2/-, so pretty standard. The second gives 2/- for Slashing, Bludgeoning, and Piercing.

Is there a difference here, or is one item's description just long winded? As far as I'm aware the 2/- item should cover all three physical damage types and nothing more, but the other item is specific about the types of damage. Is there a type of damage the second item won't cover? How will the second item interact with weapons that do multiple types of physical damage?

does it appear exactly like that?

or is it 2/S/B/P?

The specific properties are as follows:

Resistance: Bludgeoning Resist 2/-
Resistance: Piercing Resist 2/-
Resistance: Slashing Resist 2/-

The item is Deathguardian Bracers, in the old avernus shop.

then yea its essentially the same thing, maybe doing it that way made it cheaper or something but idk

It could be cheaper, but it's definitely more confusing. Thank you very much!
