Hello my name is Sticky Finish. Im going to start off by telling you why I made this guide.
I have looked around on this site and there are no good Pantheon guides at all.

I saw the highest rated guide " The IP Farmer" and laughed because it was joke.

I feel like if people are gonna look for a guide to play this hero they should not get the wrong impression on how to play him and how to play this game.

The highest rated guide for this hero on this site so far is really overrated and is telling you to basically stack damage and that it is ok to do which it is totally not. Stacking massive amounts of damage might be good for a joke and pub-stomping but against any competant player you will be crushed.

Pros

- Huge Burst damage with some small aoe
- Melee champ with ranged capabilities
- Can Gank from across the map
- Incredible Famer
- Great early game harasser
- His power during lanning phase is only matched by few

Cons

- Not a DPS champion
- Very mana dependant
- Falls off late game without a decent team

Masteries
Max offensive Pretty Standard for most AD champions.
As far as utility perseverence is one of the worst if not worst place to spend points so try not to points there EVER do that math you will see what I mean. I put a point into mana regan mastery because as I stated earlier he is very mana hungry.

Runes
Armor pentration marks and quints to maximize damage output.
Mana regan seals and glyphs will fix your mana problem by level 6 or so

Summoner Spells

Flash
Continues to be one of the best if not the best summoner spell in the game.
It can help you land kills or escape bad situations and can be used to reprosition yourself in teamfights.

Ignite
One of my favorite summoner spells helps land kills and but is also very useful for it's reduced healing effect.

In my opinion Flash/Ingite is very good on pantheon you can flash in catching them off guard and use Aegis + Heartseeker + ignite + spear toss combo to net kills easily

Other summoner spells that you are good for pantheon include

Ghost
Teleport
Cleanse
Exhuast

Pantheon is an AD burst nuker. Bloodthirster + Last Whisper currently the best item combo for ad burst champs

Frozen Mallet makes your bulkier while giving you some damage.
Pantheon is a great anti-carry Banshees Veil is a must for all anti-carries it allows you to get to their carries easier but also makes your more bulkier

Banshees Veil + Frozen Mallet gives you a lot of survivability.

Also being melee you can expect to be focused more because you have to be closer to your enemies to hit them so excpect to get CCed.

To counter this you take Mercury Treads which are the best boots in the game hands down right now.

Other good boots for panth are Boots of Swiftness and Boots of Lucidity

Banshees Veil also helps counter the crowd control.

If your dying so much and Banshees Veil is just not helping as much other great items in place of it are Guardian Angel and Renduins Omen

I did not list a 6 item above in the build sequence.

Your 6th item is always a situational item no matter what hero you are playing if a game goes on long enough to where you will get a 6th item get something that is going to sway the difference in battle. For instance if your still dying take more surviability if you already have banshees well taking renduins as well is going to help a heap load as well as being able to make or break a team fight because of its active. If you find the other team has too many ad carries and they are focusing you instead of taking Banshees Veil it could be very beneficial to take Guadian Angel + Thornmail or Thornmail + Renduins Omen Or Guardian Angel + Frozen Heart. It may be enough to still keep banshees and have any one of those defense items.

If you feel your not dealing enough damage at this point take another Bloodthirster.

Overall with this build your going to be a tanky burst nuker.

You will have plenty of damage to decimate your enemy teams carries while still being able to take a beating

I published it already so people can still see what item builds, summoner spells, masteries and runes ect. are good for Pantheon.

As stated above this guide is unfinished I will be glad to take any feedback or suggestions just comment below.
