Talk:20 Riddles in the Moonlight/@comment-28089742-20160911041900

From the event page, as long as you used one of a specific card, you can't you the same one again, cause the system counts in the INDEX of the card. That's mean you need to have 20 different leader and strong member to clear this stage 20 times to get the final rewards. Although, you could reset the used card to reuse again, but the accumulated clearance too will be reset. Some new challenge here.

Let's wait till the stage format out and check the difficulty first. If it's easy or moderate, then I'll put ONLY one strong leader and perhaps the member I will set weaker one. To put it simple, one strong leader, supportive member + same ally so that the used card count less for each clearance. Those card which have the potential as leader best leave it as leader rather than set them as member, in case out of useful leader.
