CLASH OF WILLS

Knacks cannot be applied to anyone two Tiers higher than you. If a Knack (but not Boons) breaks this rule, it will say so within the mechanical text.

For Knacks, a Clash of Wills is resolved by making opposed rolls of [Knack Skill] + [Legend or Calling dots, whichever is high]. If no Knack Skill applies, substitute Integrity.

For Boons Clash of Wills are Legend + Attribute with ties favoring the defender, but most are unrolled, as effects can cancel one another out or even out in other ways.

If a character is Tier 1 (Mortal) but possesses a Knack, they may apply their Knack for the scene with a Clash of Wills roll against another mortal. Applicable Calling is equal to 1 for this purpose (for a roll of Knack Skill + 1). If a Knack references a Clash of Wills, refer to this ruling. Trivial targets do not make Clash of Wills rolls.
