this is my build to brand
this is how you use him, mostly you just keep auto attacking then you burst your spells, use confliguation first then sear then pillar of fire
in this build you got to sell your dorans blade, before you got Infinty edge, the reason your going ad is because when your ap brand you cant kill the with one round of your spells, so you use ad so you can just destroy them before they have a chance to kill you, you get Ap runes so you can still do damage with your spells AND do insane damage with your attack damage
you can 1v1 almost any one as attack damage brand. you have simple weakness, like stuns and supress fiddle is really hard to 1v1 you have to stun him WHEN he starts to drain, warwick is mostly easy, unless he hits you hard with his ultiament, well i hope this build helps ALOt cause this build makes me a good brand. have fun and destroy some noobs =D
