In fact, in Honkai Dome Railway, we will encounter the problem of how to achieve the fatal contract achievement of Honkai Star Dome Railway from time to time. In fact, there is no need to worry, just these few small steps can solve this problem.
It is a limited challenge for the new character Jade. Players who do not have Jade can complete it by borrowing it from friends or during the trial.
The specific requirement is that the player needs to be a debt collector with the effect of Emerald's special combat skill in a battle.
By reducing the current character's health to 1 point, you can trigger the Fatal Contract achievement and obtain designated rewards.
