Thousand Sons and 2+ saves.

[Prot]

I don't have the Thousand Sons codex, and I forget the exact wording of the detachment that lets the player ignore AP if the damage is 1. 

 

The problem is that in our group we've been pretty much convinced it's not possible to increase a save from 3+ to 2+. (Typically this is by means of cover.)

 

However the Thousand Sons player in this case is insistent that his detachment rule gets around this and he can get to a 2+ save with his standard Rubrics.

 

Does this sound right?

I think your friend is correct. The relevant rules are as follows:

 

Cover

 

Quote

Each time a ranged attack is allocated to a model that has the Benefit of Cover, add 1 to the saving throw made for that attack (excluding invulnerable saving throws). Models with a Save characteristic of 3+ or better cannot have the Benefit of Cover against attacks with an Armour Penetration characteristic of 0.

 

All is Dust

Each time an attack with an unmodified Damage characteristic of 1 is allocated to a RUBRICAE model from your army, add 1 to any armour saving throw made against that attack.

 

There is no inherent rule preventing a 3+ save being improved to a 2+. This restriction is specific to the Cover rule. All is Dust does not include the restriction so Rubricae do indeed have a 2+ save against 1D weapons.
