how do defense cards work?
do they allow the bunny to roll first then if they fail use them to avoide the weapon if their cost is equal to or less than the weapon?
or you spend them without rolling to avoid dying?
also does it protect all bunnies if the weapon hurts other bunnies or just one bunny if they use the defense card?
The defense card is not related to any dice roll or cannot be combined with a dice roll, and the defense card has to be equal or greater than the weapon card. Additionally, the defense card only protects 1 bunny in the bunny circle.
However, you can make any house rule. Have fun!
