Braum'sbasic attacks and Winter's Bite each apply Concussive Blows to his target for 4 seconds, stacking up to 4 times. Once the first stack has been applied, any allied champion's basic attack on the target generates an additional stack.
Upon reaching 4 stacks, the target is stunned for 1.25 / 1.5 / 1.75 seconds and takes 26 - 196 (based on level)magic damage.
This effect cannot occur on the same target more than once every few seconds, but during this immunity period affected targets instead take 「 20% of the trigger damage 」「 5.2 - 39.2 (based on level) 」 as bonus magic damage from Braum's basic attacks and Winter's Bite.
Active:Braumdashes to the target ally, positioning himself between them and the closest enemy champion, gaining bonus armor and bonus magic resistance for 3 seconds. If his target is a champion, they also receive the same bonuses.
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.
Unbreakable has no cast time and does not interrupt Braum's previous orders.
Incoming: Damage sources coming from somewhere facing the shield. Those coming from behind will not be affected.
Projectiles: Sped up entities not classified as a unit (champions, minions, monsters, etc.)
Intercepting: A projectile hits Braum because he stands in front of the intended target. In addition to being redirected, an intercepted projectile is also destroyed after hitting Braum (although this is only applicable to pass-through projectiles)
Moving units are not intercepted under any circumstance, including dashes. Champion-summoned units (Command: Attack, Sapling Toss, etc.) are not classified as units until they hit the ground and thus will interact with Unbreakable while en route.
Projectiles whose effects trigger on collision will still happen upon hitting Braum - dealing damage, applying debuffs, creating slowing fields and marking the target as 'hit' for the purposes of Zenith Blade'sdash or Infected Cleaver's health refund.
Abilities that deal area of effect damage on-collision will only damage Braum.
If Spinning Axe hits Braum, regardless if it's the first hit on the damage reduction or not, it will always bounce back and not be destroyed. This happens even if Braum intercepts the attack for an ally though the axe will bounce back from Braum and not the intended target.
Projectile-based ground-targeted abilities that only occur upon successfully hitting the ground (Miasma, Aqua Prison, etc.) will apply their full effects to Braum but will be destroyed without affecting any other ally.
Projectiles that cannot hit Braum or his allies (such as an enemy Prismatic Barrier) will not be intercepted.
The damage reduction will affect any source of damage whose origin is in front of the shield.
