Battle card effects

Round to round, battle cards have a chance to proc an ability instead of performing its usual strike action. These abilities may provide a beneficial effect, inflict a harmful effects, heal, or the card may perform some other damaging or positive action.

Effects
An effect is a positive or negative change of state to the card. A positive effect is called a boon while a negative effect is called a status. Some are better suited to dueling while others are better for skirmishing.
