Spellcast Rolls are trait rolls that require you to use your Spellcast trait. Your Spellcast trait, if you have one, is determined by your subclass.
Spellcast Rolls are only made when a character uses a feature that requires one. A successful Spellcast Roll activates the effect as described by the feature.
Notes: > > A Spellcast Roll that can damage a target is also considered an attack roll. > > When you cast a spell, the text tells you when the effect ends. The GM can spend a Fear to end a temporary effect. If your spell doesn't specify when it ends, it ends when you choose or at a natural moment of the story. You can choose to end your spell early. > > You can cast and maintain the effects of more than one spell at the same time.
