TRANSHUMAN PHYSIOLOGY

When a PRIMARIS 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 1CP;
otherwise, it costs 2CP.
