Day of Battle events are drawn each turn, and coded Resolution Happenstances can trigger during specific draws.
How it works
Each Happenstance phase reshuffles and draws one card; a Happenstance applies its Day of Battle effect, sometimes to a ward chosen by chit draw. During resolution draws, cards coded Co (Courage), Hs (Handstrokes) or Sh (Shooting) apply only to the matching draw type, after which a fresh card is drawn.
So if the player is drawing a card for a Courage Check, and a “Co” code appears, then that card applies to the check.
