http://www.dakkadakka.com/dakkaforum/posts/list/15.page JForum - http://www.jforum.net I interpret this to mean that the +2 also applies to both armor and invulnerable saves. My justification is that the rule says it effects any save rolls.
My Brother interprets the rule to mean that it only applies to armor. His justification is that modifications like this only effect armor saves since in the rules in the big book says that units roll from their save characteristic unless their invulnerable save is better.

In simple terms, I am saying the +2 effects all saves (armor and invulnerable), while my brother says it only effects armor saves.

If however they are granted a 5+ invulnerable save through the use of the Adeptus Custodes banner, they now have a 3+ invulnerable save.


I dont think there is anything that grants Astra militarum a 4+ invulnerable but I could be wrong.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/750610/9829977.page http://www.dakkadakka.com/dakkaforum/posts/preList/750610/9829977.page GMT http://www.dakkadakka.com/dakkaforum/posts/preList/750610/9829991.page http://www.dakkadakka.com/dakkaforum/posts/preList/750610/9829991.page GMT
And to answer op yes, all saves including the invul get it ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/750610/9832540.page http://www.dakkadakka.com/dakkaforum/posts/preList/750610/9832540.page GMT AP of a weapon and they don't benefit from the bonus from cover.

In all other respects Invulnerable Saves and Saves act the same, which includes non-cover positive modifiers.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/750610/9832549.page http://www.dakkadakka.com/dakkaforum/posts/preList/750610/9832549.page GMT
