Now starting off with Pantheon solo top you will have to recognize two things. First: you need to know who you are lanning against. If you are lanning against a Riven or a Kah'Zix or somebody who rely on building pure AD, if so you will need to start off with cloth armour, 4 health pots and 1 mana pot. Getting the "Philosophers Stone" is amazing on pantheon because of the GP5 and the regen for your health and your mana. Buying "Ionian Boots of Lucidity" is optional. You can purchase any boots you wish, but remember this; Pantheon's main goal is to poke at the opponent as much as he possibly can, that is why i reccomend those boots. The "Brutalizer" is a great item on pantheon as is "Last Whisper" because of the armour penetration which affects how much damage your spear does. "Frozen Mallet" and "Guardian Angel" give you some tankyness making it easier for you to survive in team fights. "Atmas Impaler" gives you more armour and more crtical chance with the bonus AD it gives you becaus eof your Frozen Mallet" which offers you even more tankyness and AD. Exausht is a good choice if you are heading up against some heavy AD dealers and flash offers you more mobility. Hope this build works out for you guys. Have a good one :)
