Hi, my first build for mobafire (scuse my english).
I follow this build wich is mine since a long time and I never get a negativ death/kill ratio, and I often steal a lot of kill to my team mates.

Pros :

• Great ability to gank
• Great ability to initiate
• Best ability to resist
• Best taunt of the game(3 sec)
• Lot of hp
• Amazing damages
• Badass look
• HE IS A ****IN' TURTLE YEA GUYS

________________________________________________________________

Cons :

• Mana eater
• Hum let me see...wait i'm seeking something else... No nothing else sorry.

A classical 0/21/9

Resistance, life, health regen, dodge and damage. All you need in defense Tree.

Health and mana regen, experience and gold bonus in utility tree.

Classic but effective too.

Seal - Yellow Runes :

5 Greater Seal of Armor and 4 Greater Seal of Health +7 Armor and +20 Hp
or
9 Greater Seal of Vitality +175 Hp at lvl 18

Life/Armor or only life, make your choice

Glyph - Blue Runes :

9 Greater Glyph of Magic Resist

Magic Resistance, +13 RM is very usefull in early game.

Mark - Red Runes :

9 Greater Mark of Health

Life is funny. +27 Hp

Quintessence :

3 Greater Quint of Fortitude

Life is funny. +96hp

Taunt is your principal skill, use it everytime.

Shield greatly increase your resistances AND your damages by the way of your passiv. So use it without moderation.
Powerball is a polyvalent spell : Bump, gank, help mate, etc... Don't forget to use it

Your ultimate give awesomes damages, can hit turrets, etc... It got 60sec CD max so use it when you need it without hesitate.

That's why I prefer to UP taunt at first, use it under turret, that's so funny. You can use it before a teamfight to brind an ennemy at your team :3

I up Shield at second for resistance and damage (you need it in teamfight so Mid and late game).

And finally powerball 'cause this spell is not usefull for his damages but his movement bonus and his bump.

My summoner spells :

Flash Escape, initiate, gank, etc... That's a very usefull spell with your powerball
Ignite or Exhaust I prefer Ignite for ganks or against trynd/mundo/etc... but you can pick exhaust too.

If you don't like it :

You can play full support with Teleport Clarity
A little bit more tank-support with Fortify and Heal or Cleanse

All others summoners spells are bad with rammus. Ghost is the worst, you don't need it, that's a waste. If you are a ******, pick it but I told you before, don't cry after.

Normal team in front:

So, i begin with Ruby Crystal. When have to back, I take Catalyst the Protector, I follow with Mercury's Treads.

Afer some awesome taunt, I begin (and finish) my Thornmail follow by Banshee's Veil.

Banshee's Veil is a good item for magic resist and with the mana give by this one, you'll never fall oom.
Thornmail I don't explain why I chose it, I think you cab understand, if no : don't play Rammus.
Mercury's Treads are very usefull against taunt/stun/etc... so take it, that's all => You taunt, they don't. What else ?

So : We have Mercury's Treads, Banshee's Veil and Thornmail.
Now, buy sunfire cape (begin it with Giant's Belt). Now, you're a killer (better than before). Continue on Warmog's Armor and finish with another Warmog's Armor or what you want.

Why :

Full armor = Full damage (~230) = **** off carrys
Full life = Full life :3
Magic resist = **** off AP users.

With an AP Team in front of you :

Change the first Sunfire Aegis or one of your warmogs by 1 or 2 Force of Nature.

Core items :

Last 3 items :


- AP Team :


- AD Team : <Life or Armor item like another warmog or Frozen Hearth>


- Normal team :

That's all, once again : sry my english. Have fun now and Do it for TEH Lulz with the most awesome Turtle of this world (Who talked about Giant Armadillo ?! This is a turtle dude.)

So, thank you for reading, have fun. (I believe you'll not need any luck with that build)
