Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Thank you for reading my guide. I want to start off by informing you that Pantheon is by far my most played Hero on the Fields of Justice; And so many times I see people playing Pantheon that, well, just aren't too good. When played well, he is one of the best harassers capable of hitting for 1/5 to 1/4 of an enemy champions health at level 1 every 4 seconds! Pantheon is a great initiator, and with this build a great pursuer, more than capable of tower diving. Pantheon has great survivability. With some skill (and a little bit of luck) a well timed Ultimate you can turn the tide of battle in your teams favor.
So, to initiate. Throw your Spear Shot (if they back off wait for them to come close again) Then use Aegis of Zeonia, immediately after (almost instantly) use Heartseaker Strike (takes some practice, but try to hit as many enemy units as possible). After the stun wears off throw your Spear Shot again.
NOTE: At this point Non-Tanks should be dead or one hit away from death. If they are not quite dead yet. Use Ghost and Agis of Zeonia and throw your Spear one last time. And they should be dead. If your target was a tank, you may have to burn exhaust and pursue a bit longer. Please remember, until you're level 10 and have at least Phage and Boots and maybe your Brutilizer, killing Champions at a turret is discouraged. Additionally, I would avoid trying to solo kill towers until you have Ghostblade. Use it's active and own the piss out of towers (OR get out of a bad situation very quickly)
THE FASTEST WAY TO DESTROY THE ENEMY IS TO OUT-LEVEL THEM AS QUICKLY AS POSSIBLE...THIS IS ACHIEVED BY NOT DIEING!!!!!
With this build I average 28/1/7. Yes, this in a 5v5 Pre-Made with a team that trusts each other and knows how to play. I don't score as high in a Solo Queue (typically averaging 15/5/10). But as with any build. As long as you don't die a lot. You'll be owning in no time.
I hope you enjoy.
