Defence cards are cards that have a -symbol as their primary effect.
When you play a Defence card, placed it on the table in front your Hero.
You can only have one of each type of Defence card in front of your Hero at any one time:
If you play a Defence card of a type you already own, the old card is discarded.
Any -bonus provided by a Defence card is applied each turn that card is in play.
Defence cards protect your Hero and are discarded when the sum of one or more attacks made in a single turn are equal to or more than the defence value as indicated on the card near the -symbol.
Damage done to Defence cards do not carry over between turns.
