It's not a troll build, jungle Braum actually works surprisingly well. With your W to jump into a minion, auto/Q/auto them and almost insta-stun them it's actually really good for ganking.

Personally, I use a Wit's End on him, but then I tend to build him more for damage than tank (when I'm jungling at least), mainly because it works well when his passive triggers, as you've got the x-many seconds of magic damage on them.

Crit chance/damage runes are pointless, but other than that, I see nothing wrong with them. Yes, you wouldn't play with this in a Ranked game, but for normal games it's a bit of fun, just like Jungling with Twitch, Rumble etc.

Troll skill order, troll runes, troll build.

I gave it a try to scale him with ap, but with this build it´s esay to carry a game, but if you want me to I can add an ap variant of this.
Since it´s my first guide, I´m happy to hear it´s not bad and I´ll try to make it better.
Thank you for the feedback.

While this build may not be bad, it could definitely be better, especially for jungle. As he scales on ap, health, and armor, why would you not then rather go for items that help him scale? Rather than botrk, I think he'd scale better with flare for the AS passive procs (if jungle really is your goal here), or elder lizard. Just curious. Thoughts?
