Use this Stratagem in any phase, when a SALAMANDERS INFANTRY unit from your army that is not a SERVITOR and did not Advance in this phase or your previous Movement phase is chosen as the target for an attack. Until the end of that phase, when resolving an attack made with a weapon that has a Damage characteristic of 1 against a model in that unit, add 1 to the saving throw. This does not affect invulnerable saving throws.
