On the Card Hunter birthday anniversary, I feel players should be allowed to reset their quests. I don't really agree with quests being locked once they are completed, it hurts replay value of game. Quests are very fun part of co-op. Has there ever been discussion about why quests are only allowed to be done once?
This subject came up before, and I had my quests reset. I haven't done it again, and don't know if there is an interval policy, but requesting a quest reset via email to support@cardhunter.com might work for you.
It seems like there could be a lot of different criteria for reset. I would even spend pizza or gold to redo them. There are 62 levels, a gold chest costs 5 pizza, very roughly 30o pizza to reset all the levels would be fair to let people pay. This accounts for the fact that most people don't play the 1 hp quests, and people don't really do the higher difficulty quests like troll tyrant. I think for the price of a monthly club membership they could reset quests.
Or you can enter a tournament for 50 gold and get 3 gold chests. Just sayin'. I know BM has reset quests for free in the past, but if you want to pay, they might also accept cash. I'm all in favor of a little monetization to keep the game going.
I would do quests for free, it's not about chest lol I'm coop player I like the challenge and co-op different game style. Nothing to do with gold chest, but I do enter the tourneys also. Locked challenges are a part of the game replay that is gone once its done.
