は、各属性のボスを倒すことで受け取れる「禁忌の獄の証」を集めることで、☆6確定のガチャに挑戦できます。ボスは強力で、特殊なスキルや倒し方が必要になりますが、報酬も大きいので挑戦する価値があります！また、禁忌の獄の証は他のイベントでも使えるので、集めておくと役に立つことがあります。
In Monster Strike, there is a high-level Triple Mission called “Forbidden Jail”. By defeating bosses of each element, you can receive “Proof of the Forbidden Jail” which can be used to challenge a guaranteed ☆6 gacha. The bosses are powerful and require special skills and strategies to be defeated, but the rewards are also great so it’s worth challenging. The Proof of the Forbidden Jail can also be used in other events, so it’s useful to collect them.
