are armor penetration marks good for him?

Shouldn't the jungle route be Wolves, Golem, Lizard, Gank?

So difficult to follow! Do i get Philo or Spirit Stone first, or both? Should I rush Sunfire or Frozen Heart? It displays two different build paths that don't agree with each other..on the same page, I'm trying read them throughly to get a better idea, but it's getting me more confused. One says that the machete is not worth upgrading, while the other says that the spirit stone upgrade is perfectly built for rammus... Can I get some basic clarification here?

just think a bit about it ;) philo has more use if you get it earlier. so i would prefer to get it first and after it spirit. sunfire or fh is situational, if the enemies have more attackspeed you can go fh pretty good. sunfire gives you a better clear and more dmg.

Spirit Stone first. You don't rush Philospher's for that little extra gold you save by purchasing it earlier.

counters rammus:
-Darius
-Cho'gath
-Garen
-Olaf
-Teemo (hybrid)

Y thik that this guide should include some item build for using when the opposing team has lots of ap, (last game y was fucked by a katarina)(spirit vistage was not enough)

Super Guide,got 6/3/29 on first game and 5/0/35 on second this is pro :)

Awesome Guide, got 7/9/33 on my first ever jungle game, and first time using Rammus too, thank you for your contribution to the LoL community

the full game build is incorrect, aegis and runic bulwar have the same unique aura then don't stack, i sould have this build but changing aegis for spikemail and recomend de buf on bots that give u speed when u are safe in base, can go to the 1 torret in one powerball.

6 ranks of W eh?  Should definitely get the Ancient golem Stone as well.

"Machete isn't worth upgrading since the stats that you get from Madreds aren't too great and you don't rely on levels too much. On the otherhand, the Stone upgrade tree gives you a sustain item first. But if you want sustain, you might as well get a Philo stone as it is a GP5 and it transitions nicely into mid-late game items that are much more useful."

I'd argue the opposite actually, the only thing that Shurelya's gives over Spirit of the Ancient Golem is the move speed active (EDIT: Scratch this, it also gives CDR. I address that below). While the Shurelya's active is amazing, I'm not sure losing out on double the health, double the regen, 30 armour, and tenacity is worth it when it's practically guaranteed that someone else on the team will have it. Besides that, Philo stone is such an INCREDIBLY weak early item now and you give up on a lot of early game power.

EDIT: I forgot that Shurelya's also gives CDR, which with the removal of the Defensive CDR mastery is kind of a big deal. Still though, it's only 10% now and with items like the new Iceborne Gauntlet (formerly Frozen Fist) there are other good options; still, it's a consideration. I still don't think the early game power hit is worth it though, especially when the build path to SotAG is so easy; but it's a closer decision than I originally gave it credit.
