I’m theorycrafting a new character with a buddy. We’re debating the following.
Say we have a monk with access to the dissonant whispers spell from something like the Fey Touched feat. When they cast it as their action on their turn when right next to an enemy and the enemy fails the saving throw, the enemy runs away, letting us opportunity attack. Since it’s still that character's turn, does an opportunity attack count as an action, and would it let you use your bonus action to make an unarmed strike from Martial Arts?
TL;DR: Is an attack of opportunity a “an Attack action” that would trigger the monk's Martial Arts? Or is it ruled as a reaction and won’t trigger it as a result?
