How do you open the iron door in dqm joker?

Answer 1

To open the iron door in the sewers, beat the game and then beat solitaire's team (which consists of a metal kaiser slime, gigantis and mumbo-jumboh), she'll give you a key that smells of sewers that she found in the old comissioner's drawers. You can then open the door and then in there is an estark that, if you beat it, will become your monster. Tips: * Solitaire's team isn't very hard * Estark is asleep on the first round, use this to your advantage * Alabast dragon/dragonlord + estark equals dhoulmagus, which is an ingrediant to rhapthorne
