Shield Bash (Blue)

The attacking hero may choose to discard a card to avoid being dealt 1 damage.

The attacking hero can only choose to discard if they have a card in hand to discard. If they cannot discard a card (e.g. they have no cards in hand), they can not pay the cost and they will be dealt 1 damage.

Shield Bash’s effect does not apply to the controller of an attacking ally as they are not an attacking hero. The controller of the attacking ally will neither discard nor will be dealt damage from resolving Shield Bash.
