He runs out of mana pretty quick, especially with his combos,
What starting item are you folks using, and what set of runes?
I used to be able to beat garens really easily with a nearly full damage rune set, (+18 AD), then I would just get the sapphire mana crystal as my starting item, Today I didnt have that luxury though.
Curious to see how people are building him.
Demon King Maou1 votesI've played over 250 games as pantheon aswell as am mastery 7 Dslayer Pantheon atm and the only real problem about pantheon is his levels 1 - 3 after level 3 i very rarely / Never run out of mana unless im securing a kill
I generally play pantheon with 19% base armor pen runes and rush these items 
i also run these spells 
Generally get around 12 - or more kills per game with an avg 4 or more deaths per game ( Depends on how my lane goes and how my team plays )
iisabrina1 votesWhere are the armor penetration % runes?. I can only see the solid number runes.
iisabrina1 votesUsually, hes not a problem, but yesterday it was a garen (and I used to always destroy garens), but I couldnt. I was running out of mana too fast, and garen certain does a whole lot of damage,
