Hi, I'm Reaper and this is my guide on using pantheon in low-elo to win games and climb.

If you want consistent wins, you will not be able to really carry as pantheon since he falls off late game, so, once you get level 6 Grand Skyfall you want to use it as a Teleport to get your team ahead. You want to be looking towards mid or bot lane, and gank their lane, if they are behind and they can get the kill it is best to let them get it, but if you must take the kill do so. The more kills other lanes get, the harder they can carry you once you fall off.

Most people max out Q Spear Shot first, which is good for poking and getting kills. But you will lose a lot of hp in the process due to minion aggro. So if you max E Heartseeker Strike you can clear waves efficiently and poke without minion aggro.

Most people will take summoner aery since they max Spear Shot and can poke even more with it. But since we max Heartseeker Strike Electrocute works perfect for when you combo. Spear Shot Aegis of Zeonia Heartseeker Strike Spear Shot

The best combo which I briefly stated under runes is Spear Shot Aegis of Zeonia Heartseeker Strike Spear Shot It is best to Spear Shot first since by the time you use Aegis of Zeonia and Heartseeker Strike you will have Spear Shot up again to secure the kill.

You also have Ignite So you can Ignite after you use Heartseeker Strike or before you combo if you feel it can secure the kill.

With Pantheon it is better to take Ignite over Teleport since pantheons Grand Skyfall already acts as a teleport. There is no point in having 2 teleports when ignite will help with early kills and securing kills throughout the whole game.

If you are going to miss CS you can use your Spear Shot and if your mana is low you can use your Corrupting Potion to regain a lot of mana. Once your Heartseeker Strike is maxed you can clear entire waves with it fast and easy which is great for pushing waves.
