Just one more question the card says the rat swarm still counts as defeated , what that suppose to mean ?
I know that i defeat it because i got 10 but still because i didnt get 12 it is shuffle back in the deck but still defeated , so to deal with it if i encounter it again as long as it is defeated?
There are occasionally other cards (scenarios or locations) that say if a monster is defeated or undefeated do x. So when applying those other effects, you would treat the card as defeated. For instance, the Sandpoint Cathedral says:

So you would still get to add a blessing from your discard pile to your hand, even though you have to shuffle it back into the deck.
