Braum/Strategy

Skill Usage
Braum's abilities work best with allies, and as such, he should often be in a duo lane.

Unbreakable can not only be used to protect your ally, but also to protect minons, denying enemies gold.

Braum makes a very good dive partner for people who jump in, such as Jax or Jarvain. He can follow in with W, shielding them from counter CC with E, keep the target's allies away with Q and R, and stun with his passive.

Build Usage
Braum does very little damage, and does not scale very well with any offensive items. He can also take more then his fair share of attacks. As such he should primarily be building Health, Magic Resist, Armor, with some Cooldown Reduction. Braum's mana cost are low, so he generally do not need much, if any, mana or mana regeneration.
 * Since Braum can intercept auto-attacks Thornmail and Randuin's Omen can be a good choices. As Braum can make great use of their passives.
 * Mercury Threads are one of the few good ways for Braum to get Tenacity.
 * Ninja Tabi is another strong choice, but is generally less recommended, unless the enemy team has alot of auto-attackers and little CC.
 * Banshee's Veil is often a good defensive item, however it can be rather tricky to use well with Unbreakable, since both of them will "pop" with the same attack.
 * Wit's End is one of the few offensive items that synergize with Braum by removing magic resist before the passive triggers, and allowing for more of the passives post-stun on-hit damage.
 * Braum still has only a few ways to get close to a target however.
 * While it also allows him to stun slightly sooner, he will not appreciably stun more often due to the passive's cooldown.

Cooldown reduction allows Braum to keep his shield up more often, interceping and reducing more damage for his team. Fortunatly, there are many items that give both defense and cooldown reduction.

Countering
Braum's E make's him very difficult to kill, but it only protects him from one side. Walking around it will allow you to do full damage. Braum's Q is his only ranged attack and it is a skill shot. Making him fairly easy to kite.
 * Mobile Assassins like Zed or Fizz are good for jumping past his shield and getting to the squishy targets.
 * The shield does not protect Braum from Crowd Control.

Since Braum stacks defenses, % penetration (Last Whisper and Void Staff) and % health (Blade of the Ruined King, Lyandra's Torment) are very good items against him.
