Okay, for some reason the mastery tree is broken. Anyone know why this is?

I updated this page as I learned a few extra things. Hopefully this is better now.

The runes are not really as important. That is the rune set I use for regular attack characters minus the armor (Which I have maxed out dodge runes for the seals instead). What rune set works for you is what works for you. What is more important is the items and skills you get and in what order.

Hi. I have used a couple Rammus builds and I enjoy this one a lot. I am really new to the game though and I am wondering why you are using armor penetration runes? Wouldn't more defensive runes be effective? I saw another build use a lot of magic resist runes.. which makes sense to me. Could you explain that further?

Actually, maybe you should hold off until after Guardian Angel since that grants magic resistance as well. Force of Nature might be a good item to get after that.

Yep this build is definitely solid. The only thing is, at which point should I start going for magic resist against caster heavy teams? After Thornmail?

Well, Heal kinda is more important since they can't reduce your health quickly enough. Your armor actually makes the heal spell more effective.

Iunno if Heal is the better Spell to use other than Ignite or Exhaust, but if it works.

Good item layout btw.
