The build is sick matie!!!!
I played this build today and got 22 kills but the thing is your a gc!! (glaas canon) but a great build that I recommend!!

Ok first and foremost you need to completely rewrite this guide due to horrible spelling errors in it. You not only miss spell basic words but you also miss spell champion names, summoner spells, and I think you even miss spelled some item names. Second off, Pantheon is much like a mage in that you really need to focus on his spells for damage. Ditch all of the attack speed items since they are a waste on him. Get merc treads instead of zercs for starters. Drop the Black Cleaver. Get a Brutalizer but don't turn it into a Youmuu's. Drop the crit runes. Pantheon already automatically crits on targets below 15% health so you dont need to have it in your runes. Instead of crit add in armor pen, it's great early game to help you pull ahead. Oh and also max Aegis last, it's there as a utility spell and you need the extra levels in HSS instead. If the cool down is too long for you early game then you are being too reliant on it and need to pace yourself more early game. On my final note I'm gonna say fix the spelling again. Check it once, check it twice, copy and paste the guide into Microsoft word for a spell check if necessary. It's incredibly hard to take a guide seriously that is full of spelling errors.

lol...i don't know why people wants to build pantheon as a dps. he is a physical caster omg!
crit items and runes are a waste of money on him, since his q will crit only if the target is below 15% of his max health, and won't apply on hit effects. and you have no defenses...health is nothing if you get no mitigation by armor and magic resistance. you'll die in a matter of seconds in a team fight.

@FalseGod thank you for the support ill try spacing it out a little less and explain things better on my next build and thank you for the great support!
@NeoZ A little rude but the truth this was ment for killing and little sustain, i max eagis of Zeonia first because it helps a lot with the lower coldown to stop the enemy champions from attacking, i sayed later down in the build that you can take ninja tabies or mercs and that i just prefer zerkers , i take Edge on panth to make his Spear more of a execution move,English is not my first language so sorry about that ;)
@cyberfacade well i like crit runes personaly but i sayed later in the build that you can take armor pen if you want, sorry for the wall of text im new at mobafire (first guide) and thanky you for beeing positive and hope the guide helps you (if you use it)

your guild is nice. but the problem is your runes why you put critical chance runes that is a wast of runes.
and your guide is a wall of text try to make it better with some images.

Pantheon - Dieing was never so easy.
Horrible guide, Frozen Mallet as the only life item. Cleaver (and attack speed in general) isnt needed on Pantheon, swap Zerker Greaves to Mercs/Tabis. Youmuus is useless late game. Edge on Pantheon is unneeded, rather get a second Bloodthirster.
Why max Aegis of Zeonia before Heartseeker Strike? You only needed the utility the skill gives.
Your english hurts.

I'm no Pantheon authority *cough never played him*, but I know this about guides: yours has A LOT of space with just text, which becomes tiring and demotivates reading. Also, I believe you could invest a bit in explaining the combo, each skill separately and how to put them up together (for new players), perhaps even some laning advice.

Hope that helps! ;)
