@RonLugge @mikemearls @bbarlach @ChrisPerkinsDnDSpiritual Weapon = Bonus; Cantrip = Action; Yes he can attack and cast cantrip…? Yes.

@RonLugge @bbarlach @JeremyECrawford @ChrisPerkinsDnD yes, on the round after casting

Posting in case anybody looks down here and doesn’t look for other clarifying posts relative to Spiritual Weapon: unlike what Mearles says, the casting of the spell (as a BA) *also* includes it attacking, per later JC relative tweets. So you can BA cast it and attack and also cast a Cantrip, make an Attack Action, or whatever other Action in the same turn. Powerful, but as-intended.
