Also another question
Just got my WoC down from loft, need to play again.

(First off, 1's always fail)

Iron hard skin in the Army rule book says max AS +0 (model skin turns to metal etc) but main rule book says max AS +1.
(RAW, Army rule book over rules Main rule Book.)
What do you do when this EOTG get put on your Chaos knight, is it another eye closed, as it has no effect. If Main rule book win outs!!
