Hey, thanks for the question and glad to know you're enjoying hunting gods!
When you fail to Oppose a god, you take 1 point of damage according to the suit of the card you picked to determine which were the god's goals and motivations - so if you're attacked by a god who aims to Deceive or Despair, you take Pilot damage; while a god who aims to Devour or Destroy deals Slayer damage! Thanks for reaching out, we'll make sure to make that aspect clearer when we update the pdf!
