Infernal Engine

Use this Stratagem in your opponent's Shooting
phase or the Fight phase, when a Traitoris
Astartes Daemon Engine model from your army
is selected as the target of an attack. Until the
end of the phase, each time an attack is allocated
to that model, subtract 1 from the Damage
characteristic of that attack (to a minimum of 1).
If that model has the Titanic keyword, this
Stratagem costs 2CP; otherwise, it costs 1CP.
