Do modifiers that apply after the dice pool is rolled, like Nightmare, also apply to dice that cards add later?

Question

Accepted Answer

No. Those modifiers apply only to the initial dice pool, right after it is rolled and before any cards are played. Dice added later through card plays are not affected, and the designer knows of no exceptions.
