General Stratagy

The stage has a relatively simple gimmick of applying a debuff on enemies when the scarecrow is healed. This debuff makes it easier to clear out waves of enemies, allowing you to get a faster clear. The strategy for this stage is simple, start out by healing the scarecrow, then follow it up with your damage dealer’s EX Skill. An exception to this rule is S.Hina on wave 2 and onwards, as there are more than 5 enemies that will be on the field. You will want to use 1 S.Hina EX Skill first, followed by healing the scarecrow, and then finish off the remaining enemies with another S.Hina EX.


Team Building

Unlike most content in the game, this JFD stage incentivizes running fewer students to get the additional Cost Recovery at stage 4. This makes it ideal to bring only 2-3 students per team to maximize the benefits of this effect. In addition to this, Gehenna students receive a 100% ATK buff which makes them the ideal choice for damage dealers. As for what roles to fill, we recommend 1-2 Gehenna AoE damage dealers and 1 healer. You can bring either a Mystic or Explosive damage dealer depending on your roster. Feel free to bring along general supports if your team lineup benefits from it, such as NY.Fuuka + Hina.
