In the world of HorrorVale all monsters fall under one of 7 Elemental categories.
Bone, Flesh, Blood, Nature, Electricity, Ectoplasm, and Mystery.
Identifying the creatures that fall under each Element is important, because you’ll find that certain attacks and abilities fall under an Element themselves!
All of the Elements have their own Strengths and Weaknesses, and it’s important to learn them for maximum success in battle.
