...That about covers the Incantations. What Rituals are left?
I wouldn't force you to actually pick an Asset with conjuration (And even allow casting when that Mythos card has blanked the reserve, so pointless casting is fine there...
I disagree with this one. We had a situation where the reserve was empty for the rest of the game. I discarded conjuration simply to reduce the number of cards in my possession. How could one successfully cast conjuration if there was nothing to conjure?
