If you have levels of Monk 1/Bladesinger 4, do you stack the Intelligence AC bonus?

@JeremyECrawford If you have levels of Monk 1/Bladesinger 4, do you stack the Intelligence AC bonus on top of the normal Monk Dex+Wis?

A bonus applies as long as you don't already have a bonus from the same feature/effect. #DnD https://t.co/G1cgx0yZwh

@PerestaMASo does that mean no? Just like when you try to combine monk with mage armor? That means yes. A bonus goes on top of an AC calculation.

@PerestaMAbut don’t both set your ac at a value and not “give a bonus?” Bladesong explicitly gives you a bonus.
