This golden badge is usually given to wizards who either excel at or who have master abjuration magic as a symbol of their accomplishments. While wearing this badge, you always have the shield spell prepared if you know it, and it doesn't count against the number of spells you can have prepared. In addition, whenever you cast the shield spell, you can take another reaction before the start of your next turn. This second reaction can't be used to cast the shield spell again.
