The dangerous magic that dominates the Plague Lands has an effect on all life within its confines. Rammus is a living example. No one is entirely certain how an armadillo from the Shurima Desert made his way through the ***ungu Jungle - much less unharmed - but he did just that. Caught in a burst of wild magic, Rammus began to evolve. In the matter of a week, he was man-sized and a week after that he had achieved sentience. The question became, what now? There really wasn't a place in the world for a sentient armadillo - except in the League of Legends. His new form was certainly equipped to fight, and especially to defend. However, it was Rammus' newfound sense of humor that led him to craft an outrageous suit of armor to go over his natural protection ? giving birth to the fearsome Armordillo!

I like using flat armor and magic resist runes which gives us a lot of survaliblity early game. Flat hp quints can conpensate us lack of doran's items in main build.

Start from regrowth pedant and one health potion. Try laning until you will have enough money for Giant's Belt and Boots of Speed. Try buying some potions anytime you are in base. After that, depending on what damage source enemies are focused pick Negatron Cloak or Chain Vest, then second of these two. This is my core which I use almost always. Rest of items are situational but I showed some of that I mainly use. Warmog's Armor could be controversial because many player really don't like it but I find it very, very useful mid game. That boost of health and health regen allows me be in the middle of teamfight much longer what results bigger amount of taunts and knocks from powerball. I'm sure your team will appreciate this.

These are depending on personal preferences. In my opinion flash is a must-have for chasing and escaping but if you don't like fortify you can replace it with teleport, ignite or even clarity.

I hope this build will be as much useful as it is for me. I'm waiting for your feedback and experiences. Please DON'T vote without testing it.
