Braum me to the shielded...
Braum's shield can be a bit monotous. After all it is only damage reduction.
So here is idea.
Unbreakable Active: Braum raises his shield in the target direction, creating a barrier that intercepts incoming non-turret enemy projectiles and reduces the damage he takes through the shield. The first instance of damage blocked by his shield is negated completely.
At end of duration, shield form a ice wave which pushes all nearby enemies back. Pushes only bit around shield in opposite direction to Braum. It can be with dmg also.
