I'd get 2xDorans. Either ways, Atmog's? WIN.

i meant ISNT an auto attacker.

hmm overall a pretty nice guide/build, but i would really like some more info on exactly how Triforce is beneficial for him. Imo triforce is expensive and although it gives decent stats, they are only mediocre. It doesnt do much to boost your dmg seeing as ur dmg is from ad, and thats smoething triforce doesnt give a whole lot of. I get that triforce has the proc, but pantheon is exactly an autoattacker. i think something like last whiperer or bloodthirster would benefit him more. Also another thing is ur skilling order. You max out heartseeker first...but then you stagger stun and spearshot...i dont get it. lvling stun doesnt do anything except make it do more dmg, and very poor dmg at that. I wont + or -, cause im feeling nice today :P, but i think u shud adress these issues.

Thanks for all of the feedback, and believe it or not late game even with resistances you can dish out large chunks of damage.
leaguesdf:
i know i just wanted it to be flashy and more noticable for people to read, like i said this is my first guide, i will end up putting icons and item pictures and all that nice stuff, but i just haven't figured it out or put the time into it yet.

Hmmm and i would change the item order a bit but anyway :P.

Nice build and guide although i would like to add some more Arp somehow because late game you wont deal as much damage as you should(unless your enemies dont build resistances at ALL).

I will +1 for the build. I love it.
The only problem with the is with the runes. First, Flat AD runes are better for autoattackers champ, and Armor pen are better for champs who do alot of damage from physial abilities. Like pantheon. so Arp are better on him.
however, if u still want it for early game damage, swich the between the marks and quints.
Arp marks are the best marks. 17 Arp holy ****. Flat AD marks only bring 10. While For quints, they both bring about the same(7 AD, 9 Arp). So take Arp marks and Flat AD quints.

U need to work on your guide. more pics, icons, formating, and less color!!
