Like a certain gun toting witch from Platinum Games, Gretchen also has an arsenal of magical traps. She’s the witch in Knights Contract that cursed Heinrich with immortality. While players can’t control Gretchen, she can make ethereal bear traps and guillotines appear to dice up demons.
With powers like these you may wonder why Heinrich is carrying Gretchen like a princess. Protecting Gretchen one of the key gameplay mechanics. If she dies in the jaws of a hungry demon, Heinrich dies too.
