Braum Ability (LoL): Concussive Blows

Braum's attacks apply Concussive Blows for 4 seconds. Enemies with Concussive Blows gain additional stacks from any ally's attacks.

At 4 stacks, the target is stunned for 1.25 / 1.5 / 1.75 seconds and takes 26−196 magic damage (depending on level). For the next 8 / 6 / 4 seconds (levels 1 / 6 / 11) they don't receive stacks, but take an additional 20% of the trigger damage from Braum's attacks.
