Pantheon Build .
I use ignite for the extra damage early game and clarity to stay in lane .
Basic 21 - 0 - 9 Masteries - included both ignite and clarity .
Since the patch buffs your 'e' ability like crazy, i max that out first . At level 2 with both 'w' and 'e' you can kill someone pretty quickly .
I start with a doran's blade for extra dmg early game for easy first blood and a hp pot in case im low. Then I get boots and another blade and return to lane after first blood. Later on, when im richer, I strive for a quick bloodthirster and then my infinity edge. If the game is not over yet, stack B.F. swords and then change them to bloodthirsters.
I've won many games with this build and goodluck with it !
