Gandalf starts with Nosy if he is a Meddler. It says: Once per round you may look at the top card of any hero's skill deck...
Is there a time during the round you are not allowed to trigger this? Let's say Dis is going to be attacked and is in Darkness. Can she defend the attack, use her ability to put a card on top of her deck with a fate icon, and then you trigger Nosy to look at the top card and give her an inspiration, then move the app on to the Darkness step?
I am just unsure if 'once per round' is the same as 'at any point in the round'.
thanks!
