Well hello everybody and welcome to my first guide.
I know pantheon pretty well since it's one of my main characters.
In this build you'll see how I build this pretty offensive Pantheon.

Since I don't have a lot of armor pen on that build, my three quints will be Greater Quintessence of Desolation. You could also pick Greater Quintessence of Might to add more AD and take Last Whisper as sixth item as you'll ses later.

Next thing you'll want to improve is its AD with 9 Greater Marks of Might.

I had also Greater Seal of Endurance for my build on Volibear and they seemed pretty useful on Pantheom giving him some survivability. It might also help for a more tankish build of him but even on an AD build, I keep them. Anyway, takind AD Seals does't add much AD so you'd better invest in something more particuliar to Seals.

Finally I take 9 Greater Glyphes of Celerity or its cooldowns. Even if they're not that high, it allows you to spam them especially late game.

For the masteries as you can see it's all in offense. ***Section needs completion...

Explaining the items, since Pantheon is a mana *****, build Manamune first. You can take either boots or a Long Sword to begin with, it depends of your playstyle. Right after Manamune, take a Vampiric Scepter : Life Steal is always good when farming minions and it starts building your Bloodthirster. Only then finish building your boots of Mobility. I like very fast heroes you can take Ninja Tabi, Ionian Boots of Lucidity, Mercury's Thread or Berserker's Greave if you prefer : they're all good choices. When you have your Bloodthirster, take Sheen. Why ? After using an ability, bonus damage. Hints, W : Basic Attack : E : Basic Attacks hurts like hell. If they run away, use your Q ... it doesn't forgives. Instead of upgrading to Trinity Force already, build Infinity Edge first. You'll deal a lot more damage but of you want more balance, upgrage Trinity already. Since this build is intended AD, Infinity first. When you got your Trinity, well the last item is yours. you can pick Black Cleaver (like I did here which I don't do often) to blast armor, Phantom Dancer for attack and movement speed, Madred's Razorblades for a bit of balance and tank destroying, Last Whisper for more armor pen, whatever you think necessary in the game.

Skill sequence is pretty easy. E first. For farming and against level 1 heroes it hurts pretty much. Then your W. The stun is all you need and I suggest maxing it only at the very end. Then your Q at level 3. After that, E is your first priority, then Q, then W. At levels 6, 11 and 16, pick your ult point. E and Q deals the majority of your damage and the W doesn't deals much. The only think you could worry about is its cooldown as it lowers at each level.
