I Made this build because i got Brand the second day out and i love his abilities and his AOE burst damage he is a very fun champ to play but he requires a little bit of skill to play as you have to plan where to place his AOE and his skillshot here in the following chapters i will explain my Strategies with him.

I chose Flat Magic Pen. runes for my Makrs and Quints because having that 34 Penetration into thier resist even if they didnt buy any items for it will increase your damage significantly i got mana Glyphs and MP5 seals because it really sucks to run out of Mana in the middle of a fight then get screwed over because you couldnt finish people off quick enough.

I made a 12/0/18 Mastery build for this character that gies him some damage and mana regen bonuses but also gives him amazing leveling/farming capability so that he can get money quick and get his items faster .

My items mainly depend on if you csan do well and get 20 stacks on Mejais Soulstealer even if you dont do that as long as you make it through the rest of the build you will have an amazing amount of AP and will Majorly Own most people you fight. -Especially Squishies =D-
I pick of Sorcs Shes for obvious reasons but you might be able to switch them out for Ionian boots if you REALLY want CD reduction i buy Archangels next for the mana and the fact that the mana to AP boost is amazing thats why i get 2 plus with rabadons giving a 30% increase you might be able to get above 850 AP with this

i chose to upgrade Pillar and sear first because i believe they are the best combo together pillar allows you to Harrass and farm minions easily and then sear can stun your enemies whiel you pull of your comboes on them a second time and most likley seriously injuring and/or killing them.

i choose ignite and clarity because the bonus 10 ability power from the ignite mastery helps alot early game and try fighting Mundo with it Mundo "Sadism! HA HA i cant die" Brand "Ignite! sorry no more health regen for you -Comboes mundo to death-.
and Clarity for those sticky situations where you need mana NOW or else you wont get that triple kill or ace, its helped me many times

Other great alternitives are Flash for Escape and possibly Heal if you cant Survive well

one of my favorite things to do Early game is sit there and spam pillar of flame on the enemy infront of me and his minions you will run out of mana fast but thats what clarity is for and if you aim well enough with it it will probably even get you a kill especially once you get sear you can pillar > Sear > Pillar again while theier stunned for amazing affect
late game i like to start a gank with pillar leading into a sear stun then i will use pyroclasm and stun them again with sear whiel i use pillar again most of the time though they should die before the second pillar plus with the magic Pen you have your Pasive will do even more damage to them so you might even get a kill after they run

Well this Sums up my build i hope you all like it. i use this build alot and it seems to work out pretty well Please Leave feedback and ideas for the build =)
