I absolutely agree. I guess I just got lucky, the vast majority of the "blood exchange" places were some kind of damage up, and I found a lot of blood by clicking the pots, I even found 3 in one room! Kinda cheesy but I found if I sit with weakened enemies and my 5 Guard I got early, I can build threat and farm Gallantry required to use the cards. It's crazy the kind of luck or strategies (or cheeses) real players come up with when you give them your game.
