	Malignant Body Cache Crafted Cache Contains a Gurgling Head, Blackened Femur, or Trembling Hand used for summoning a powerful enemy beneath the Tree of Whispers within Malignant Burrow.
	Uncertain Heart Magic Crafted Cache Contains a random Caged Heart, with a chance at a Wrathful Heart. By mulching malignant hearts, and mixing them into an awful slurry before purifying them, powers both strange and terrible can be had.
	Uncertain Invoker Magic Crafted Cache Contains a random Malignant Invoker, with a chance at a Wrathful Invoker. Cormond hasn't exactly explained why making these requires essences of other Malignant Hearts, but once thrust into a pustule, a more powerful Malignant is brought forth.
