Two Edges, Same Blade.
Full Blooded Sorcery
Being a Full-Blooded Sorcerer means that you have the potential to Master all the Knacks and abilities of your Heritage. Each Sorcery has three 3 tiers of mastery: Apprentice, Adept, and Master. Each tier unlocks a set of benifits that increase the potency of you abilities.
After purchacing Full-Blooded Sorcery, you will have 7 Sorcery Points to put into your Sorcerous Knacks at Character creation. No one of which may be higher than 3 at character creation. (Just like normal Skill Knacks.)
To be an Apprentice, you only need to have access to the knacks.
To be an Adept, you must have 4 knacks at rank 4.
To be a Master, you must have 5 Knacks at rank 5.
(Some sorceries only have 5 knacks but others have the potential to have quite a few more.)
