I just saw a new card from echoes of the past mythos pack Led Astray: Choose one - Put one of your clues on a cultist enemy or 1 doom on the current agenda
My question is can you choose the first option even if you dont have any clues? I remember wondering about this in the Undimensioned & Unseen scenario where if i remeber correctly, the squid token from the chaos bag gave you the option of either healing a brood or removing one clue from it.
