The Emperor Protects

Play this tactic during the Priority phase of any round,
after Roll for Priority, but before Ready Fighters.
Until the end of the round, all friendly Cawdor fighters gain a 5+ save which cannot be modified.
If this roll is attempted and failed, any Serious
Injury results on the Injury dice are treated as
Out of Action instead. Fighters may choose
not to use this save if they wish.
