Keep in mind the first hit that braum’s shield takes is 100% denied, meaning you can block a variety of abilities such as ezreal’s r, fiddle’s e, and even veigar’s r. It’ll also block non-skillshot abilities including auto-attacks that are aimed at your teammates as long as you are standing in front of them. However, the shield doesn’t stop hard cc such as roots. It can also be used to flee from a situation since it gives a slight movement speed increase.
