Damage reduction

[Vrakyas]

I've got 2 items that grant me damage reduction:
Guardian's Helmet: 10/Slash, Pierce
Guardian's Cloak: 10/Pierce, Bludgeon and 10/Slash, Bludgeon

So my character sheet shows:
10/Pierce, Bludgeon
10/Slash, Bludgeon
10/Slash, Pierce

So does it mean, that I have a damage reduction of 10 against all melee attacks? or is it 0?

I'm going with reduction of 10 against all melee attacks.

Hammerblock V covers Bludgeon
Axeblock V covers Slash
Spearblock V covers Pierce

Anyone else have an opinion (or facts) regarding the above guess?
