Build and Runes
Braum must land Winter’s Bite or a basic attack to start Concussive Blows. If you get marked, exit combat range before getting hit 3 more times to avoid the stun.
Unbreakable gives Braum extremely strong directional defense, either wait until it is down or outposition the ability.
Avoid grouping up in a line so Braums ult won’t hit a lot of your team.
Do you not caught by his ulti in the jungle, in the narrow paths it can be hard to get out of the slow on the ground.
Be wary of standing next to enemy minions, as it provides Braum the opportunity to dash next to you. Once caught in melee with his Winter’s Bite (Q) still up it is hard to escape him.
