Hello. This is my first guide. I make this guide for Pantheon because he is my favorite champion in League of Legends.

First I want to tell you that you have to TRY this build first before you will vote. This build is for players who know what Pantheon can do and this is the way I play now Pantheon after I try a lot of builds.

Finally you have to find a build who fit you style to play.

This build is focused especially on much armor penetration, attack speed, life steal and attack damage.

Some updates at skill sequence.

Pros

- he own early game
- he is a good assassins, and with his ultimate can catch you and kill you
- he have nice damage, and a nice single target nuke with his Q
- he looks like a real Spartan
- nice passive,who allow him to tower dive easy

Cons

- no ability to escape
- he is a bit squishy
- his ultimate is very easy to avoid

For runes I go for 9x Greater Mark of Desolation You need this for your spear to cause more damage
9x Greater Seal of Scaling Mana Regeneration This will solve a bit you mana problems. Anyway you won't use your spells so much early. Focus more on farming minions.
Then I go for 9x Greater Glyph of Magic Resist This give you with you masteries around 45-50 magic resistance at start.
For Quintessence I take 1x Greater Quintessence of Desolation for extra armor penetration and 2x Greater Quintessence of Health for extra health. Very important early on.

I take 21-9-0 masteries page. I take 21 in offense because Pantheon need all extra damage early on where he shine, and I also put one point in Cripple to improve my Exhaust spell.
Then I put 9 points in defense for much more resistance early.

Why I maximize Heartseeker Strike first?

Pantheon is an early to mid champion so I maximize this first and I can do a lot of damage with W-E. A bit harass with Q and the rest damage from W-E. But careful, I suggest you to keep your mana for the right time, when you want to kill someone, especially with new patch you can spam this ability more than before so watch out you mana.

Then I maximize Spear Shot a single target nuke with a low cooldown. Use this a bit to harass before you want to jump on them with Aegis of Zeonia and unleash you E.

With new patch your Aegis of Zeonia will stun for 1 second at all ranks so I put only one point early.

Exist another possibility of maximize skills. If you face an champion who have nice harass potential you can maximize Spear Shot first, so you can harass hard with this skill.

As Summoner Spells I take Flash and Exhaust

I take because Pantheon doesn't have an escape ability so this spell can save his life or you can use it to get closer to an enemy to chase him down.

I use because you can use it against AD carry or even you can use it to escape from someone who chase you.

I start with a Doran's Blade if enemy team don't have harassers or with Boots and 3x Health Potion if they have a lot of harassers.

Then, when I go back I take The Brutalizer This items will give you not only attack damage but it will give you cooldown reduction and +15 armor penetration. This is a lot early.

With the new patch Pantheon have a low cooldown to his ability so he can use them much more. I suggest you to take Chalice of Harmony early if you want to play more aggressive. This item fits well with Pantheon and you can sell it later for better choice.

I upgrade Boots into Mercury's Treads for magic resistance and reduced crowd control.

Next item will be Emblem of Valour Now stop a bit there. Maybe some people will say that this item is bad, this item is useless or is not worth the price. When you upgrade this item to Zeke's Harbinger it will worth it. And why? With your masteries and with your you will have around 50-55 armor penetration. And I say that is huge for low armor champions. You will hit them like a boss with and with Your job is to focus carry and squishy targets. Besides that you will have some atack speed, life steal and an aura for your team mates. An Xin Zhao, Ashe, Master Yi and so on, will love this aura.

Finish you Youmuu's Ghostblade Take B. F. Sword and upgrade to Black Cleaver

At this time you will have very nice burst, nice life steal, attack speed and a LOT OF armor penetration. Get it?

Your next item will be Bloodthirster Final item is situationally. You can take Frozen Mallet for extra health and some damage. You can also take, if you feel you want more damage, Infinity Edge This is one of the best attack damage item and also give you an increased critical damage.

If you feel you need more resistance you can take Guardian Angel This items allow you to die once, then revive and fight again. Is just awesome.

Another situational item can be Last Whisper if the enemy will stack much armor.

Now, Pantheon can go and dominate a lane with many other champion for example Leona I personally prefer champions who have crowd controls.

You are an assassin, so you job in team fights is to stay back and don't get focused. Then when they last expect just jump on them and chase them down. Try to always focus carry and squishy target.

Pantheon need a good team to be very good not only early, but even late game, where he is not as strong as another champions.

Early game you have to focus a lot on farming minions. The big difference between 20 minions killed and 80 is an almost Early you have a very nice damage. If you have a good lane partner you can work with him and make a kill or more. This will give Pantheon chance to become very strong. Try to be a bit aggressive, if you don't lane against harassers. If you lane against harassers like Ezreal Ashe Miss Fortune and so on play much safe and try to farm as much as you can.

In mid game you must have already and even Emblem of Valour Try to look at minimap, and help you team mates with a gank, because with you ultimate you have a very nice potential to gank.

You continue to focus on farming minions, and when the lane phase is broken, try to avoid to being ganked. You have no escape ability so take care.

In mid game start the team fights, so you have to do your job as an assassin. NEVER EVER initiate a fight or go in front of your team. This is your tank job. Try to use bush and stay hide before a team fight starts, just to don't be focused.

Now if you doing well you have Youmuu's Ghostblade Zeke's Harbinger Black Cleaver With this items you have a very nice damage but now you depends very much on team so try the best to avoid being focused by enemy team. The longer you stay alive in team fights, the better you can hurt enemy.

At final I want to tell you that I accept any opinions and please give me your advice if you think I do it wrong somewhere. If I forgot to wrote something I will update later

This is the way I play Pantheon and I tell you again:FIRST TRY IT THEN YOU VOTE IT

Thank you for viewing and reading my build.
