heyyy @JeremyECrawford – does Shield Master allow a character to take no damage on a successful DEX save against an AOE spell? https://t.co/jwTqkS5Yo1

The 3rd benefit of Shield Master works against any effect, including a spell, that allows you to make a Dex. save to take 1/2 damage. #DnD https://t.co/s3f08XxgyU
