Flavor
Flavors are groups of special abilities the GM and players can use to alter a character type to make it more to their liking or more appropriate to the genre or setting. For example, if a player wants to create a magic-using thief character, she could play an Adept with stealth flavoring. In a science fiction setting, a Warrior might also have knowledge of machinery, so the character could be flavored with technology.
At a given tier, abilities from a flavor are traded one for one with standard abilities from a type. So to add the Danger Sense stealth flavor ability to a Warrior, something else—perhaps Bash—must be sacrificed. Now that character can choose Danger Sense as they would any other first-tier warrior ability, but they can never choose Bash.
The flavors available are stealth, technology, magic, combat, and skills and knowledge.
