I don't have the rules in front of me so I may be using different terminology to that used in the rules.
Suppose I am playing as the Scoundrel and have taken the perk that allows me to add "(draw another card and) +1" battle cards to my deck. Now suppose I make an "Attack 3" on a monster. I draw one of my "(draw another card and) +1" cards. I duly draw another card, and it is my Critical Miss card.
Am I allowed to apply the effect of the Critical Miss card first, then apply the +1 after that? In other words, in what order do I do things?
- first multiply by 0 (for the Critical Miss), giving 0, then add 1, giving 1?
- first add 1 (giving 4), then multiply by 0, giving 0?
- my choice of the above?
Or is there no ordering to be done and it's a blank "if the Critical Miss card is drawn and it applies to the attack, then the attack deals no damage to the opponent, no matter what other cards were drawn"?
