In a faraway place known as Lokfar there was a seafaring marauder called Kegan Rodhe. As was his people's way, Kegan sailed far and wide with his fellows, stealing treasures from those unlucky enough to catch their attention. To some, he was a monster; to others, just a man. One night, as they sailed through the arctic waters, strange lights danced over the frozen wastes. There was something hypnotic about them; it was something that drew them to it like moths to a flame. Trekking across the frozen waste, they came to a cave covered in ancient runes. The meaning of the runes long lost to them, Kegan led the way inside. There, inside a perfect cage of ice floated a dancing column of flame. There was no way such a thing should be burning, especially not in this place. However, its movement was as hypnotic as a siren's song, captivating and seductive. While the others stayed back, Kegan could not help but approach it while holding out his hand...

That is the last thing Kegan Rodhe remembers, for now his body belongs to Brand. It is a creature of olden times, perhaps even a casualty of the Rune Wars. It is known in ancient texts as the Burning Vengeance. It is a creature of pure fiery hate that exists for no other reason than to lay waste the world of men and yordles. No one is quite sure how Brand found his way to Valoran, but he began his predations at once. Overcome by Demacian forces, he was given a choice: fight within the confines of the League or die. Naturally, he chose to use his destructive powers in the League, for now...

''This place will burn, not by cinder flying or breath of wind, but by the vengeance of my hand.''

This is what i use every time i play him and it works out rather well although if the enemy team is building magic resist i rather build the void staff other then the morello's evil tome.
I would also suggest that you always try to sear someone then confligrate them and use your pillar of flame so that you get that 25% damage boost to all hit but the pillar, other then that i usually conflagration then then use sear to stun them so they have no chance in dodging the pillar of flame. If you do this during games it should end up making you very successful when using brand. That just about raps it up with my summary GL and HF when using this build with brand. xD
