>Chaos Mastery means causing a blood clot to form, or making someone trip and snap their leg, or any number of Fate related methods of creating those conditions or situations.
These are two options under Chaos Mastery:
>>• The mage manipulates brain chemistry to cause hallucinations or produce emotional responses, imposing suitable Conditions such as Swooning, Guilty, or Broken.
>• The mage manipulates the subject’s body to create complex medical conditions, causing appropriate Conditions such as Addicted, Disabled, or Blind.
You are telling me that, by chance, someone's brain and body chemistry could, within a span of three seconds, just so happen to align in such a way to make them spontaneously broken inside for a non-negligible duration, or paralyze them for a non-negligible duration.
Why are the brain and body allowed to mutate in such absurdly unlikely negative fashions, but not allowed to mutate in such a way as to bolster a body's muscles or nerves, or a brain's cognitive abilities?
>Forge Destiny is manipulating the strands of Fate to create a Chosen Hero. Using a pop culture example, it's unlocking the X-Gene in someone to turn them into a mutant.
You are also telling me that the strands of Fate can be woven to create a pyrokinetic/electrokinetic/cryokinetic superhero (or even a superhero who shifts around their body's properties with biokinesis) within a span of three seconds, but not a super-strong or super-intelligent superhero. Why is this the case?
Fate can grant blessings and hexes, but it can bless people in ways other than granting one of the listed boons (exactly what Forge Destiny does), and it can hex people in ways outside of the listed hexes (Chaos Mastery goes well outside of the realm of the listed hexes).
