@JeremyECrawford. Can I misty step (bonus), fire bolt (action) and fireball (surge) on same turn? Or need action surge also be a cantrip?

In that situation, the Action Surge spell would also need to be a cantrip. #DnD https://t.co/deCcV0mYM1

@JeremyECrawford if Action Surge is another complete action why does the spell need to be a cantrip? Thx. https://t.co/Rre7upzFPI

@tclayton The rule on bonus action spells pertains to your whole turn, not to a particular action (PH, 202).
