Hello Summoners! Welcome to the new Brand! Also this Build is not yet complete, the basics are ready bur I am still experimenting with the Runes. THIS IS MY FIRST GUIDE SORRY IF ITS NOT WELL DEVELOPED Also read the NOTES for more info.
I've been playing Brand for a few months and I've experimented on a few different type of builds. The builds I've seen on the inter-webs are all pretty much the same, start with the Ring, get the Scepter, get the mask, etc, etc... Yes, those builds gives Brands amazing AP but I've always felt that we can rebuild him., make him a little more well rounded, it doesn't haft to be all AP with Brand. I've notice he can get very tanky if you build him right. So this is my attempt.
Brand is an over all well rounded champion This build will show you how to capitalize on all that Brand can offer. Thank you for taking the time out of your busy day to check out this build.

So the Core build for Brand seems to be Liandry's Torment, Rylai's Crystal Scepter,
Rabadon's Deathcap SO because of this I've used this as my basic, my foundation to go tanky based off of the health you get from Liandry and Rylai I went a step farther. I went and got Spirit Visage. I soon realize I could tank the towers early on which was great help for the team to get the towers early on while the tower focused me. Puss it gives you Magic Resist and 20% cool down that goes along with Athene's Unholy Grail's 20% cool-down reduction that gives you the full 40% cool-down reduction that equals out to awesomeness.
Start with Mana Regen first, after you get the blue cup start getting health, after health get AP, after you have Rylai's start getting Haunting Guise for more HP, once you have the gold buy it. NOW start getting SPECTRE'S COWL build into SPIRIT VISAGE finish LIANDRY'S TORMENT some where along the lines get the boots but do not upgrade until after you have all these listed. Finally get ATHENE'S UNHOLY GRAIL and for your last item get anything AP/ Magic Pen.
As you can see STARTING this build you need alot of Amphilifing Tones and Ruby Crystals. This goes along with Brand just fine.
SO in review you have CD reduction maxed. You have MR, extra Health, Ap and Mana Regen. Your last item is up to you... Death Cap, Zhona or any other high AP item to top off the build. Or get more Magic Pen items.
ALSO get health potions and Exilir of Brilliance as much as possible as well as Wards. Wards saves lives! and play smart/ safe.
