Makeshift Armour

One of your fighters can spend an action to play
this card.
Tuck this card under the fighter's card; while
it is there, their armour save is treated as one
point better than it is (a 5+ Save is treated as
a 4+ Save, for example). If any save roll for
the fighter is a 1 (before modifiers), discard
this card after resolving the attack(s).
