Say I pick the two ability cards for my turn in Gloomhaven. One of them has an attack action on top and the other card has an attack action on the bottom. I'd like to perform the top action first and there's a chance it will kill the monster I'm targetting, but this could still be prevented by the ability modifier deck.
Is it possible for me to use the bottom ability conditionally? To use it as an attack action if my first action doesn't kill the monster, but use it as the standard Move 2 action if it does kill the monster?
I had a look at the rule book (p 18) to see if it would be of any help, but couldn't find anything addressing this situation:
On a character’s turn, he or she will perform the top action of one of the two ability cards played and the bottom action of the other. The leading card designation used to determine initiative is no longer significant. Either card can be played first for its top or bottom action. When playing a card’s action, the abilities of the action must be done in the order written and can’t be interrupted by the action on the other card. As soon as the action of a card is completed, it is immediately placed in the appropriate area (discard pile, lost pile, or active area) before anything else happens. Players are typically free to choose not to perform any part of the action on their card, however, they must perform any part that will cause a negative effect (e.g., reduce hit points, lose cards, or cause a negative condition) on themselves or their allies.
The next section on the Move 2 and Attack 2 actions isn't much help either:
Players can also use any card they play as an “Attack 2” action on the top half or a “Move 2” action on the bottom. If a card is used this way, it is always discarded, regardless of what is printed on the card. On their turn, before, during, or after performing their two actions, players can use any number of items they have equipped.
Is there any more information clarifying this?
