@KeatonStamps @JeremyECrawfordDoes a mundane shield count as armor with respect to the Mage Armor spell? no – the rules categorize shields and armor as two separate things

@KeatonStamps @JeremyECrawford so, if a rule says "X doesn't work if you wear armor" it would have to specific shields, too, to include them
