Theres no blocking in lorcana, theres nothing you can do to stop your opponent from gaining lore (questing). This is why you couldnt do anything while demoning the game when your opponent quested. When you opponent goes to quest, theres no responces you can do so i think you were confusing the timing of tapping to challenge. Yes you can tap your character to attack it but only on your turn and you cant attack it during your opponents turn and challenge it to stop questing.
I think you’re confused about what I was saying. When someone goes questing I can challenge, they were not letting me challenge at all. Even if they gain the lore first, I should still be able to challenge to remove their character from the game as mine was big enough to do so. I was not questing at all, but was also told I could not challenge with unexerted wet or dry characters.
@JestaThaRogue Oh ok, then they were wrong. You can definitely challenge on your turn with your dry Active characters so I am not sure why they told you otherwise. I thought you were trying to challenge in response to them questing, and this is what they were telling you that you could not do.
