Lingering Composition:
You add a flourish to your composition to extend its benefits. If your next action is to cast a cantrip composition with a duration of 1 round, attempt a Performance check. The DC is usually a standard-difficulty DC of a level equal to the highest-level target of your composition, but the GM can assign a different DC based on the circumstances. The effect depends on the result of your check.
Critical Success The composition lasts 4 rounds.
Success The composition lasts 3 rounds.
Failure The composition lasts 1 round, but you don't spend the Focus Point for casting this spell.
What would the DC be at level 2, 5 and 8 let's say, and how do you calculate it? What does "a standard-difficulty DC of a level equal to the highest-level target of your composition" mean?
It’s the DC chart in the GM chapter. Look up DC in the glossary.
Ohh I see, so DC 16 at level 2, DC 20 at level 5, DC 24 at level 8. That's not too brutal with good Performance. Thanks!
