The Perdo Corpus guidelines state:
Level 5: Do superficial damage to a body (for example, remove its hair).
Level 10: Cause a person pain, but do no real damage. Cause the loss of one Fatigue level.
Level 15: Do one Body level of damage to a person. Destroy a person’s limb. Destroy a corpse.
Level 20: Destroy one of a person’s major senses. Do two Body levels of damage.
Level 25: Age someone five years. Do three Body levels of damage.
Level 30: Inflict a major disease. Do four Body levels of damage.
Level 40: Kill a person.
My character is interested in creating a spell that does multiple levels of fatigue instantly rather than Body damage levels; do they scale up as per the body levels?
So Two Body Levels == Three Fatigue Levels?
