TRUESILVER ARMOUR

Use this Stratagem in any phase, when a GREY KNIGHTS CORE INFANTRY unit from your
army is selected as the target of an attack. Until
the end of the phase, each time an attack is made against that unit, an unmodified wound roll of
1-3 for that attack fails, irrespective of any
abilities that the weapon or the model making the attack may have. If that unit contains 5 or fewer models, this Stratagem costs 2CP; otherwise,
it costs 3CP.
