Knacks are a new type of trait for ICONS, neither ability, specialty, nor power. A knack can have one of the following effects, chosen when the knack is created and acquired:
- Substitutes one ability level for another in relation to a specific kind of test or usage. Examples include swapping Strength for Willpower for intimidating (“My might is intimidating!”) or Intellect for Coordination for Dodging (“Totally saw that one coming.”).
- Provides a +2 bonus for a specific type of test in the form: “Because I [something unique about the character] I get a bonus when I [particular situation or test].” For example, “Because I once belonged to the criminal underworld, I get a bonus when I interact with criminals on their own terms.”
- Provides the effects of a power at a level equal to a “linked” ability. Note that this does not count as the “Ability-Linked” limit for powers that feature it (see the Great Power sourcebook for details).
- Provides a declared benefit the player can bring into play based on a specific Specialty, reflecting the character’s knowledge, experience, or resources. For example, “As a Business Expert, I know a lot of people in this field. One of them should be able to help us out.” This follows the same guidelines as a retcon (ICONS, p. 80).
