The game is very specific about what you should do and how you should do it. If you fail a Perception check rather than a combat check to defeat a Cave Lizard, you still suffer Combat damage. When you are blessed, you get to add a die; you don’t get to add your modifiers again. If you play Pharasma’s Knowing to draw 2 cards then recharge 2 cards when you have only 1 card in your deck, you can’t recharge the first card before drawing the second to avoid dying; you have to draw both at once, which will kill you. A power that happens when you examine a card does not happen if you look at it while you are not examining.
