As a braum main, ive tried many different builds and realised that there is only 1 ultimate build which would win bot lane no matter the match up, no matter the team composition, no matter how good or bad you are with braum, or even reading the map , csing and all those other tiny details that league of legends entails.
So here it is! My braum guide. Do take note, that you can do this build for the jungle. Just swap out the sightstone for the attack speed jungle item.

This guide was made by me but i had forgot to sign up and i didnt know you couldnt take ownership so here i am.

As soon as you've brushed your moustache a couple of times, laning phase would be really really simple. You just have to walk up, and by that time, everyone should be running the hell away from your manliness. If you do happen to have a statikk shyv already during the latest part of the laning phase, then by all means you already have won the game.

Now this is the tricky part. You NEED an ekko to do this who has also built a statikk shyv. Once you lockdown an enemy with ANY skill or even an auto attack, let the ekko RFC in with a statikk shyv. In 0.02 seconds, you'll notice that the enemy is stunned. This is when you put ur shield up and start kicking him with your 30% crit chance. Ekko will then be stabbing with his 80% crit chance and you would end up with a scene where the mafia is beating up a poor little champion.

As soon as you get your first staikk syhv, Build another. The enemy will soon realise what you're doing and will have no choice but to surrender to your manliness. You're welcome ;)
